  /**
    An `Ember.Binding` connects the properties of two objects so that whenever
    the value of one property changes, the other property will be changed also.
  
    ## Automatic Creation of Bindings with `/^*Binding/`-named Properties.
  
    You do not usually create Binding objects directly but instead describe
    bindings in your class or object definition using automatic binding
    detection.
  
    Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
    instances. The value of this property should be a string representing a path
    to another object or a custom binding instance created using Binding helpers
    (see "One Way Bindings"):
  
    ```
    valueBinding: "MyApp.someController.title"
    ```
  
    This will create a binding from `MyApp.someController.title` to the `value`
    property of your object instance automatically. Now the two values will be
    kept in sync.
  
    ## One Way Bindings
  
    One especially useful binding customization you can use is the `oneWay()`
    helper. This helper tells Ember that you are only interested in
    receiving changes on the object you are binding from. For example, if you
    are binding to a preference and you want to be notified if the preference
    has changed, but your object will not be changing the preference itself, you
    could do:
  
    ```
    bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
    ```
  
    This way if the value of `MyApp.preferencesController.bigTitles` changes the
    `bigTitles` property of your object will change also. However, if you
    change the value of your `bigTitles` property, it will not update the
    `preferencesController`.
  
    One way bindings are almost twice as fast to setup and twice as fast to
    execute because the binding only has to worry about changes to one side.
  
    You should consider using one way bindings anytime you have an object that
    may be created frequently and you do not intend to change a property; only
    to monitor it for changes (such as in the example above).
  
    ## Adding Bindings Manually
  
    All of the examples above show you how to configure a custom binding, but the
    result of these customizations will be a binding template, not a fully active
    Binding instance. The binding will actually become active only when you
    instantiate the object the binding belongs to. It is useful, however, to
    understand what actually happens when the binding is activated.
  
    For a binding to function it must have at least a `from` property and a `to`
    property. The `from` property path points to the object/key that you want to
    bind from while the `to` path points to the object/key you want to bind to.
  
    When you define a custom binding, you are usually describing the property
    you want to bind from (such as `MyApp.someController.value` in the examples
    above). When your object is created, it will automatically assign the value
    you want to bind `to` based on the name of your binding key. In the
    examples above, during init, Ember objects will effectively call
    something like this on your binding:
  
    ```javascript
    binding = Ember.Binding.from("valueBinding").to("value");
    ```
  
    This creates a new binding instance based on the template you provide, and
    sets the to path to the `value` property of the new object. Now that the
    binding is fully configured with a `from` and a `to`, it simply needs to be
    connected to become active. This is done through the `connect()` method:
  
    ```javascript
    binding.connect(this);
    ```
  
    Note that when you connect a binding you pass the object you want it to be
    connected to. This object will be used as the root for both the from and
    to side of the binding when inspecting relative paths. This allows the
    binding to be automatically inherited by subclassed objects as well.
  
    This also allows you to bind between objects using the paths you declare in
    `from` and `to`:
  
    ```javascript
    // Example 1
    binding = Ember.Binding.from("App.someObject.value").to("value");
    binding.connect(this);
  
    // Example 2
    binding = Ember.Binding.from("parentView.value").to("App.someObject.value");
    binding.connect(this);
    ```
  
    Now that the binding is connected, it will observe both the from and to side
    and relay changes.
  
    If you ever needed to do so (you almost never will, but it is useful to
    understand this anyway), you could manually create an active binding by
    using the `Ember.bind()` helper method. (This is the same method used by
    to setup your bindings on objects):
  
    ```javascript
    Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
    ```
  
    Both of these code fragments have the same effect as doing the most friendly
    form of binding creation like so:
  
    ```javascript
    MyApp.anotherObject = Ember.Object.create({
      valueBinding: "MyApp.someController.value",
  
      // OTHER CODE FOR THIS OBJECT...
    });
    ```
  
    Ember's built in binding creation method makes it easy to automatically
    create bindings for you. You should always use the highest-level APIs
    available, even if you understand how it works underneath.

  /**
    A computed property transforms an object literal with object's accessor function(s) into a property.
  
    By default the function backing the computed property will only be called
    once and the result will be cached. You can specify various properties
    that your computed property depends on. This will force the cached
    result to be recomputed if the dependencies are modified.
  
    In the following example we declare a computed property - `fullName` - by calling
    `.Ember.computed()` with property dependencies (`firstName` and `lastName`) as leading arguments and getter accessor function. The `fullName` getter function
    will be called once (regardless of how many times it is accessed) as long
    as its dependencies have not changed. Once `firstName` or `lastName` are updated
    any future calls (or anything bound) to `fullName` will incorporate the new
    values.
  
    ```javascript
    let Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: Ember.computed('firstName', 'lastName', function() {
        let firstName = this.get('firstName'),
            lastName  = this.get('lastName');
  
        return firstName + ' ' + lastName;
      })
    });
  
    let tom = Person.create({
      firstName: 'Tom',
      lastName: 'Dale'
    });
  
    tom.get('fullName') // 'Tom Dale'
    ```
  
    You can also define what Ember should do when setting a computed property by providing additional function (`set`) in hash argument.
    If you try to set a computed property, it will try to invoke setter accessor function with the key and
    value you want to set it to as arguments.
  
    ```javascript
    let Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: Ember.computed('firstName', 'lastName', {
        get(key) {
          let firstName = this.get('firstName'),
              lastName  = this.get('lastName');
  
          return firstName + ' ' + lastName;
        },
        set(key, value) {
          let [firstName, lastName] = value.split(' ');
  
          this.set('firstName', firstName);
          this.set('lastName', lastName);
  
          return value;
        }
      })
    });
  
    let person = Person.create();
  
    person.set('fullName', 'Peter Wagenet');
    person.get('firstName'); // 'Peter'
    person.get('lastName');  // 'Wagenet'
    ```
  
    You can overwrite computed property with normal property (no longer computed), that won't change if dependencies change, if you set computed property and it won't have setter accessor function defined.
  
    You can also mark computed property as `.readOnly()` and block all attempts to set it.
  
    ```javascript
    let Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: Ember.computed('firstName', 'lastName', {
        get(key) {
          let firstName = this.get('firstName');
          let lastName  = this.get('lastName');
  
          return firstName + ' ' + lastName;
        }
      }).readOnly()
    });
  
    let person = Person.create();
    person.set('fullName', 'Peter Wagenet'); // Uncaught Error: Cannot set read-only property "fullName" on object: <(...):emberXXX>
    ```

    This helper returns a new property descriptor that wraps the passed
    computed property function. You can use this helper to define properties
    with mixins or via `Ember.defineProperty()`.
  
    If you pass a function as an argument, it will be used as a getter. A computed
    property defined in this way might look like this:
  
    ```js
    let Person = Ember.Object.extend({
      init() {
        this._super(...arguments);
  
        this.firstName = 'Betty';
        this.lastName = 'Jones';
      },
  
      fullName: Ember.computed('firstName', 'lastName', function() {
        return `${this.get('firstName')} ${this.get('lastName')}`;
      })
    });
  
    let client = Person.create();
  
    client.get('fullName'); // 'Betty Jones'
  
    client.set('lastName', 'Fuller');
    client.get('fullName'); // 'Betty Fuller'
    ```
  
    You can pass a hash with two functions, `get` and `set`, as an
    argument to provide both a getter and setter:
  
    ```js
    let Person = Ember.Object.extend({
      init() {
        this._super(...arguments);
  
        this.firstName = 'Betty';
        this.lastName = 'Jones';
      },
  
      fullName: Ember.computed('firstName', 'lastName', {
        get(key) {
          return `${this.get('firstName')} ${this.get('lastName')}`;
        },
        set(key, value) {
          let [firstName, lastName] = value.split(/\s+/);
          this.setProperties({ firstName, lastName });
          return value;
        }
      });
    })
  
    let client = Person.create();
    client.get('firstName'); // 'Betty'
  
    client.set('fullName', 'Carroll Fuller');
    client.get('firstName'); // 'Carroll'
    ```
  
    The `set` function should accept two parameters, `key` and `value`. The value
    returned from `set` will be the new value of the property.
  
    _Note: This is the preferred way to define computed properties when writing third-party
    libraries that depend on or use Ember, since there is no guarantee that the user
    will have [prototype Extensions](http://emberjs.com/guides/configuring-ember/disabling-prototype-extensions/) enabled._
  
    The alternative syntax, with prototype extensions, might look like:
  
    ```js
    fullName: function() {
      return this.get('firstName') + ' ' + this.get('lastName');
    }.property('firstName', 'lastName')

    The purpose of the Ember Instrumentation module is
    to provide efficient, general-purpose instrumentation
    for Ember.
  
    Subscribe to a listener by using `Ember.subscribe`:
  
    ```javascript
    Ember.subscribe("render", {
      before: function(name, timestamp, payload) {
  
      },
  
      after: function(name, timestamp, payload) {
  
      }
    });
    ```
  
    If you return a value from the `before` callback, that same
    value will be passed as a fourth parameter to the `after`
    callback.
  
    Instrument a block of code by using `Ember.instrument`:
  
    ```javascript
    Ember.instrument("render.handlebars", payload, function() {
      // rendering logic
    }, binding);
    ```
  
    Event names passed to `Ember.instrument` are namespaced
    by periods, from more general to more specific. Subscribers
    can listen for events by whatever level of granularity they
    are interested in.
  
    In the above example, the event is `render.handlebars`,
    and the subscriber listened for all events beginning with
    `render`. It would receive callbacks for events named
    `render`, `render.handlebars`, `render.container`, or
    even `render.handlebars.layout`.

    The `Ember.Mixin` class allows you to create mixins, whose properties can be

      edit: function() {
        console.log('starting to edit');
        this.set('isEditing', true);

    // .extend.
    App.CommentView = Ember.View.extend(App.Editable, {
      template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
    });
  
    commentView = App.CommentView.create();
    commentView.edit(); // outputs 'starting to edit'
    ```
  
    Note that Mixins are created with `Ember.Mixin.create`, not
    `Ember.Mixin.extend`.
  
    Note that mixins extend a constructor's prototype so arrays and object literals
    defined as properties will be shared amongst objects that implement the mixin.
    If you want to define a property in a mixin that is not shared, you can define
    it either as a computed property or have it be created on initialization of the object.
  
    ```javascript
    //filters array will be shared amongst any object implementing mixin
    App.Filterable = Ember.Mixin.create({
      filters: Ember.A()
    });
  
    //filters will be a separate  array for every object implementing the mixin
    App.Filterable = Ember.Mixin.create({

    //filters will be created as a separate array during the object's initialization

    NOTE: This is a low-level method used by other parts of the API. You almost
    never want to call this method directly. Instead you should use
    `Ember.mixin()` to define new properties.
  
    Defines a property on an object. This method works much like the ES5
    `Object.defineProperty()` method except that it can also accept computed
    properties and other special descriptors.
  
    Normally this method takes only three parameters. However if you pass an
    instance of `Descriptor` as the third param then you can pass an
    optional value as the fourth parameter. This is often more efficient than
    creating new descriptor hashes for each property.

    Ember.defineProperty(contact, 'firstName', {
      writable: true,
      configurable: false,
      enumerable: true,
      value: 'Charles'
    });
  
    // define a simple property
    Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
  
    // define a computed property
    Ember.defineProperty(contact, 'fullName', Ember.computed('firstName', 'lastName', function() {
      return this.firstName+' '+this.lastName;
    }));
    ```
  
    @private
    @method defineProperty
    @for Ember
    @param {Object} obj the object to define this property on. This may be a prototype.
    @param {String} keyName the name of the property
    @param {Descriptor} [desc] an instance of `Descriptor` (typically a
      computed property) or an ES5 descriptor.
      You must provide this or `data` but not both.
    @param {*} [data] something other than a descriptor, that will
      become the explicit value of this property.

  /**
    Schedules an item to run from within a separate run loop, after
    control has been returned to the system. This is equivalent to calling
    `run.later` with a wait time of 1ms.
  
    ```javascript
    run.next(myContext, function() {
      // code to be executed in the next run loop,
      // which will be scheduled after the current one
    });
    ```
  
    Multiple operations scheduled with `run.next` will coalesce
    into the same later run loop, along with any other operations
    scheduled by `run.later` that expire right around the same
    time that `run.next` operations will fire.
  
    Note that there are often alternatives to using `run.next`.
    For instance, if you'd like to schedule an operation to happen
    after all DOM element operations have completed within the current
    run loop, you can make use of the `afterRender` run loop queue (added
    by the `ember-views` package, along with the preceding `render` queue
    where all the DOM element operations happen).
  
    Example:
  
    ```javascript
    export default Ember.Component.extend({
      didInsertElement() {
        this._super(...arguments);
        run.scheduleOnce('afterRender', this, 'processChildElements');
      },
  
      processChildElements() {
        // ... do something with component's child component
        // elements after they've finished rendering, which
        // can't be done within this component's
        // `didInsertElement` hook because that gets run
        // before the child elements have been added to the DOM.
      }
    });
    ```
  
    One benefit of the above approach compared to using `run.next` is
    that you will be able to perform DOM/CSS operations before unprocessed
    elements are rendered to the screen, which may prevent flickering or
    other artifacts caused by delaying processing until after rendering.
  
    The other major benefit to the above approach is that `run.next`
    introduces an element of non-determinism, which can make things much
    harder to test, due to its reliance on `setTimeout`; it's much harder
    to guarantee the order of scheduled operations when they are scheduled
    outside of the current run loop, i.e. with `run.next`.

    This method should be used when an event may be called multiple times

  /**
    Strongly hint runtimes to intern the provided string.
  
    When do I need to use this function?
  
    For the most part, never. Pre-mature optimization is bad, and often the
    runtime does exactly what you need it to, and more often the trade-off isn't
    worth it.
  
    Why?
  
    Runtimes store strings in at least 2 different representations:
    Ropes and Symbols (interned strings). The Rope provides a memory efficient
    data-structure for strings created from concatenation or some other string
    manipulation like splitting.
  
    Unfortunately checking equality of different ropes can be quite costly as
    runtimes must resort to clever string comparison algorithms. These
    algorithms typically cost in proportion to the length of the string.
    Luckily, this is where the Symbols (interned strings) shine. As Symbols are
    unique by their string content, equality checks can be done by pointer
    comparison.
  
    How do I know if my string is a rope or symbol?
  
    Typically (warning general sweeping statement, but truthy in runtimes at
    present) static strings created as part of the JS source are interned.
    Strings often used for comparisons can be interned at runtime if some
    criteria are met.  One of these criteria can be the size of the entire rope.
    For example, in chrome 38 a rope longer then 12 characters will not
    intern, nor will segments of that rope.

      The `property` extension of Javascript's Function prototype is available
      when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
      `true`, which is the default.
       Computed properties allow you to treat a function like a property:
       ```javascript
      MyApp.President = Ember.Object.extend({
        firstName: '',
        lastName:  '',
         fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
        }.property() // Call this flag to mark the function as a property
      });
       var president = MyApp.President.create({
        firstName: 'Barack',
        lastName: 'Obama'
      });
       president.get('fullName'); // 'Barack Obama'
      ```
       Treating a function like a property is useful because they can work with
      bindings, just like any other property.
       Many computed properties have dependencies on other properties. For
      example, in the above example, the `fullName` property depends on
      `firstName` and `lastName` to determine its value. You can tell Ember
      about these dependencies like this:
       ```javascript
      MyApp.President = Ember.Object.extend({
        firstName: '',
        lastName:  '',
         fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
           // Tell Ember.js that this computed property depends on firstName
          // and lastName
        }.property('firstName', 'lastName')
      });
      ```
       Make sure you list these dependencies so Ember knows when to update
      bindings that connect to a computed property. Changing a dependency
      will not immediately trigger an update of the computed property, but
      will instead clear the cache so that it is updated when the next `get`
      is called on the property.
       See [Ember.ComputedProperty](/api/classes/Ember.ComputedProperty.html), [Ember.computed](/api/#method_computed).
       @method property

    `isEqual` is a more specific comparison than a triple equal comparison.

       These functions will be invoked when a matching `{{action}}` is triggered
      from within a template and the application's current route is this route.
       Actions can also be invoked from other parts of your application
      via `ActionHandler#send`.
       The `actions` hash will inherit action handlers from
      the `actions` hash defined on extended parent classes
      or mixins rather than just replace the entire hash, e.g.:
       ```js
      App.CanDisplayBanner = Ember.Mixin.create({
        actions: {
          displayBanner: function(msg) {
            // ...
          }
        }
      });
       App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
        actions: {
          playMusic: function() {
            // ...
          }
        }
      });
       // `WelcomeRoute`, when active, will be able to respond
      // to both actions, since the actions hash is merged rather
      // then replaced when extending mixins / parent classes.
      this.send('displayBanner');
      this.send('playMusic');
      ```
       Within a Controller, Route, View or Component's action handler,
      the value of the `this` context is the Controller, Route, View or
      Component object:
       ```js
      App.SongRoute = Ember.Route.extend({
        actions: {
          myAction: function() {
            this.controllerFor("song");
            this.transitionTo("other.route");
            ...
          }
        }
      });
      ```
       It is also possible to call `this._super(...arguments)` from within an
      action handler if it overrides a handler defined on a parent
      class or mixin:
       Take for example the following routes:
       ```js
      App.DebugRoute = Ember.Mixin.create({
        actions: {
          debugRouteInformation: function() {
            console.debug("trololo");
          }
        }
      });
       App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
        actions: {
          debugRouteInformation: function() {
            // also call the debugRouteInformation of mixed in App.DebugRoute
            this._super(...arguments);
             // show additional annoyance
            window.alert(...);
          }
        }
      });
      ```
       ## Bubbling
       By default, an action will stop bubbling once a handler defined
      on the `actions` hash handles it. To continue bubbling the action,
      you must return `true` from the handler:
       ```js
      App.Router.map(function() {
        this.route("album", function() {
          this.route("song");
        });
      });
       App.AlbumRoute = Ember.Route.extend({
        actions: {
          startPlaying: function() {
          }
        }
      });
       App.AlbumSongRoute = Ember.Route.extend({
        actions: {
          startPlaying: function() {
            // ...
             if (actionShouldAlsoBeTriggeredOnParentRoute) {
              return true;
            }
          }
        }
      });
      ```

       If the `ActionHandler` has its `target` property set, actions may

  /**
    This mixin implements Observer-friendly Array-like behavior. It is not a
    concrete implementation, but it can be used up by other classes that want
    to appear like arrays.
  
    For example, ArrayProxy is a concrete classes that can
    be instantiated to implement array-like behavior. Both of these classes use
    the Array Mixin by way of the MutableArray mixin, which allows observable
    changes to be made to the underlying array.
  
    Unlike `Ember.Enumerable,` this mixin defines methods specifically for
    collections that provide index-ordered access to their contents. When you
    are designing code that needs to accept any kind of Array-like object, you
    should use these methods instead of Array primitives because these will
    properly notify observers of changes to the array.
  
    Although these methods are efficient, they do add a layer of indirection to
    your application so it is a good idea to use them only when you need the
    flexibility of using both true JavaScript arrays and "virtual" arrays such
    as controllers and collections.
  
    You can use the methods defined in this module to access and modify array
    contents in a KVO-friendly way. You can also be notified whenever the
    membership of an array changes by using `.observes('myArray.[]')`.
  
    To support `Ember.Array` in your own class, you must override two
    primitives to use it: `length()` and `objectAt()`.
  
    Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
    mixin. All `Ember.Array`-like objects are also enumerable.

  /**
    This mixin defines the common interface implemented by enumerable objects
    in Ember. Most of these methods follow the standard Array iteration
    API defined up to JavaScript 1.8 (excluding language-specific features that
    cannot be emulated in older versions of JavaScript).
  
    This mixin is applied automatically to the Array class on page load, so you
    can use any of these methods on simple arrays. If Array already implements
    one of these methods, the mixin will not override them.
  
    ## Writing Your Own Enumerable
  
    To make your own custom class enumerable, you need two items:
  
    1. You must have a length property. This property should change whenever
       the number of items in your enumerable object changes. If you use this
       with an `Ember.Object` subclass, you should be sure to change the length
       property using `set().`
  
    2. You must implement `nextObject().` See documentation.
  
    Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
    to your class and you will be able to enumerate the contents of your object
    like any other collection.
  
    ## Using Ember Enumeration with Other Libraries
  
    Many other libraries provide some kind of iterator or enumeration like
    facility. This is often where the most common API conflicts occur.
    Ember's API is designed to be as friendly as possible with other
    libraries by implementing only methods that mostly correspond to the
    JavaScript 1.8 API.

    /**
      __Required.__ You must implement this method to apply this mixin.
       Implement this method to make your class enumerable.
       This method will be called repeatedly during enumeration. The index value
      will always begin with 0 and increment monotonically. You don't have to
      rely on the index value to determine what object to return, but you should
      always check the value and start from the beginning when you see the
      requested index is 0.
       The `previousObject` is the object that was returned from the last call
      to `nextObject` for the current iteration. This is a useful way to
      manage iteration if you are tracing a linked list, for example.
       Finally the context parameter will always contain a hash you can use as
      a "scratchpad" to maintain any other state you need in order to iterate
      properly. The context object is reused and is not reset between
      iterations so make sure you setup the context with a fresh state whenever
      the index parameter is 0.
       Generally iterators will continue to call `nextObject` until the index
      reaches the current length-1. If you run out of data before this
      time for some reason, you should simply return undefined.
       The default implementation of this method simply looks up the index.
      This works great on any Array-like objects.
       @method nextObject
      @param {Number} index the current index of the iteration
      @param {Object} previousObject the value returned by the last call to
        `nextObject`.
      @param {Object} context a context object you can use to maintain state.

  /**
    The `Ember.Freezable` mixin implements some basic methods for marking an
    object as frozen. Once an object is frozen it should be read only. No changes
    may be made the internal state of the object.
  
    ## Enforcement
  
    To fully support freezing in your subclass, you must include this mixin and
    override any method that might alter any property on the object to instead
    raise an exception. You can check the state of an object by checking the
    `isFrozen` property.
  
    Although future versions of JavaScript may support language-level freezing
    object objects, that is not the case today. Even if an object is freezable,
    it is still technically possible to modify the object, even though it could
    break other parts of your application that do not expect a frozen object to
    change. It is, therefore, very important that you always respect the
    `isFrozen` property on all freezable objects.
  
    ## Example Usage
  
    The example below shows a simple object that implement the `Ember.Freezable`
    protocol.
  
    ```javascript
    Contact = Ember.Object.extend(Ember.Freezable, {
      firstName: null,
      lastName: null,
  
      // swaps the names
      swapNames: function() {
        if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
        var tmp = this.get('firstName');
        this.set('firstName', this.get('lastName'));
        this.set('lastName', tmp);
        return this;
      }
  
    });
  
    c = Contact.create({ firstName: "John", lastName: "Doe" });
    c.swapNames();  // returns c
    c.freeze();
    c.swapNames();  // EXCEPTION
    ```
  
    ## Copying
  
    Usually the `Ember.Freezable` protocol is implemented in cooperation with the
    `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
    return a frozen object, if the object implements this method as well.

    It is important to use the methods in this class to modify arrays so that
    changes are observable. This allows the binding system in Ember to function
    correctly.
  
  
    Note that an Array can change even if it does not implement this mixin.
    For example, one might implement a SparseArray that cannot be directly
    modified, but if its underlying enumerable changes, it will change also.

    Note that an Enumerable can change even if it does not implement this mixin.
    For example, a MappedEnumerable cannot be directly modified but if its

    ## Adding Objects
  
    To add an object to an enumerable, use the `addObject()` method. This
    method will only add the object to the enumerable if the object is not
    already present and is of a type supported by the enumerable.

  /**
    ## Overview
  
    This mixin provides properties and property observing functionality, core
    features of the Ember object model.
  
    Properties and observers allow one object to observe changes to a
    property on another object. This is one of the fundamental ways that
    models, controllers and views communicate with each other in an Ember
    application.
  
    Any object that has this mixin applied can be used in observer
    operations. That includes `Ember.Object` and most objects you will
    interact with as you write your Ember application.
  
    Note that you will not generally apply this mixin to classes yourself,
    but you will use the features provided by this module frequently, so it
    is important to understand how to use it.
  
    ## Using `get()` and `set()`
  
    Because of Ember's support for bindings and observers, you will always
    access properties using the get method, and set properties using the
    set method. This allows the observing objects to be notified and
    computed properties to be handled properly.
  
    More documentation about `get` and `set` are below.
  
    ## Observing Property Changes
  
    You typically observe property changes simply by using the `Ember.observer`
    function in classes that you write.
  
    For example:
  
    ```javascript
    Ember.Object.extend({
      valueObserver: Ember.observer('value', function(sender, key, value, rev) {
        // Executes whenever the "value" property changes
        // See the addObserver method for more information about the callback arguments
      })
    });
    ```
  
    Although this is the most common way to add an observer, this capability
    is actually built into the `Ember.Object` class on top of two methods
    defined in this mixin: `addObserver` and `removeObserver`. You can use
    these two methods to add and remove observers yourself if you need to
    do so at runtime.
  
    To add an observer for a property, call:
  
    ```javascript
    object.addObserver('propertyKey', targetObject, targetAction)
    ```
  
    This will call the `targetAction` method on the `targetObject` whenever
    the value of the `propertyKey` changes.
  
    Note that if `propertyKey` is a computed property, the observer will be
    called when any of the property dependencies are changed, even if the
    resulting value of the computed property is unchanged. This is necessary
    because computed properties are not computed until `get` is called.
  
    @class Observable
    @namespace Ember
    @public
  */
  exports.default = _emberMetalMixin.Mixin.create({

    /**
      Retrieves the value of a property from the object.
       This method is usually similar to using `object[keyName]` or `object.keyName`,
      however it supports both computed properties and the unknownProperty
      handler.
       Because `get` unifies the syntax for accessing all these kinds
      of properties, it can make many refactorings easier, such as replacing a
      simple property with a computed property, or vice versa.
       ### Computed Properties
       Computed properties are methods defined with the `property` modifier
      declared at the end, such as:
       ```javascript
      fullName: function() {
        return this.get('firstName') + ' ' + this.get('lastName');
      }.property('firstName', 'lastName')
      ```
       When you call `get` on a computed property, the function will be
      called and the return value will be returned instead of the function
      itself.
       ### Unknown Properties
       Likewise, if you try to call `get` on a property whose value is
      `undefined`, the `unknownProperty()` method will be called on the object.
      If this method returns any value other than `undefined`, it will be returned
      instead. This allows you to implement "virtual" properties that are
      not defined upfront.
       @method get
      @param {String} keyName The property to retrieve
      @return {Object} The property value or undefined.
      @public
    */
    get: function (keyName) {
      return _emberMetalProperty_get.get(this, keyName);
    },

    /**
      To get the values of multiple properties at once, call `getProperties`
      with a list of strings or an array:
       ```javascript
      record.getProperties('firstName', 'lastName', 'zipCode');
      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
      ```
       is equivalent to:
       ```javascript
      record.getProperties(['firstName', 'lastName', 'zipCode']);
      // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
      ```
       @method getProperties
      @param {String...|Array} list of keys to get
      @return {Object}
      @public
    */
    getProperties: function () {
      for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {
        args[_key] = arguments[_key];
      }

      return _emberMetalGet_properties.default.apply(null, [this].concat(args));
    },

    /**
      Sets the provided key or path to the value.
       This method is generally very similar to calling `object[key] = value` or
      `object.key = value`, except that it provides support for computed
      properties, the `setUnknownProperty()` method and property observers.
       ### Computed Properties
       If you try to set a value on a key that has a computed property handler
      defined (see the `get()` method for an example), then `set()` will call
      that method, passing both the value and key instead of simply changing
      the value itself. This is useful for those times when you need to
      implement a property that is composed of one or more member
      properties.
       ### Unknown Properties
       If you try to set a value on a key that is undefined in the target
      object, then the `setUnknownProperty()` handler will be called instead. This
      gives you an opportunity to implement complex "virtual" properties that
      are not predefined on the object. If `setUnknownProperty()` returns
      undefined, then `set()` will simply set the value on the object.
       ### Property Observers
       In addition to changing the property, `set()` will also register a property
      change with the object. Unless you have placed this call inside of a
      `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
      (i.e. observer methods declared on the same object), will be called
      immediately. Any "remote" observers (i.e. observer methods declared on
      another object) will be placed in a queue and called at a later time in a
      coalesced manner.
       @method set
      @param {String} keyName The property to set
      @param {Object} value The value to set or `null`.

    /**
      Adds an observer on a property.
       This is the core method used to register an observer for a property.
       Once you call this method, any time the key's value is set, your observer
      will be notified. Note that the observers are triggered any time the
      value is set, regardless of whether it has actually changed. Your
      observer should be prepared to handle that.
       You can also pass an optional context parameter to this method. The
      context will be passed to your observer method whenever it is triggered.
      Note that if you add the same target/method pair on a key multiple times
      with different context parameters, your observer will only be called once
      with the last context you passed.
       ### Observer Methods
       Observer methods you pass should generally have the following signature if
      you do not pass a `context` parameter:
       ```javascript
      fooDidChange: function(sender, key, value, rev) { };
      ```
       The sender is the object that changed. The key is the property that
      changes. The value property is currently reserved and unused. The rev
      is the last property revision of the object when it changed, which you can
      use to detect if the key value has really changed or not.
       If you pass a `context` parameter, the context will be passed before the
      revision like so:
       ```javascript
      fooDidChange: function(sender, key, value, context, rev) { };
      ```
       Usually you will not need the value, context or revision parameters at
      the end. In this case, it is common to write observer methods that take
      only a sender and key value as parameters or, if you aren't interested in
      any of these values, to write an observer that has no parameters at all.
       @method addObserver
      @param {String} key The key to observer

      Registers a factory that can be used for dependency injection (with

       A simple example:
       ```javascript
      var App = Ember.Application.create();
       App.Orange = Ember.Object.extend();
      App.register('fruit:favorite', App.Orange);
      ```
       Ember will resolve factories from the `App` namespace automatically.
      For example `App.CarsController` will be discovered and returned if
      an application requests `controller:cars`.
       An example of registering a controller with a non-standard name:
       ```javascript
      var App = Ember.Application.create();
      var Session = Ember.Controller.extend();
       App.register('controller:session', Session);

      App.ApplicationController = Ember.Controller.extend({
        needs: ['session']
      });
      ```
       Registered factories are **instantiated** by having `create`
      called on them. Additionally they are **singletons**, each time
      they are looked up they return the same instance.
       Some examples modifying that default behavior:

      App.inject(<full_name or type>, <property name>, <full_name>)
      App.inject('route', 'source', 'source:main')
      App.inject('route:application', 'email', 'model:email')
      ```
       It is important to note that injections can only be performed on
      classes that are instantiated by Ember itself. Instantiating a class
      directly (via `create` or `new`) bypasses the dependency injection
      system.
       **Note:** Ember-Data instantiates its models in a unique manner, and consequently
      injections onto models (or all models) will not work as expected. Injections
      on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
      to `true`.

    Send an `action` with an `actionContext` to a `target`. The action, actionContext
    and target will be retrieved from properties of the object. For example:
     ```javascript
    App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
      target: Ember.computed.alias('controller'),
      action: 'save',
      actionContext: Ember.computed.alias('context'),

     The `target`, `action`, and `actionContext` can be provided as properties of

     ```javascript
    App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
      click: function() {
        this.triggerAction({
          action: 'save',

            // to the current controller
      }
    });
    ```
     The `actionContext` defaults to the object you are mixing `TargetActionSupport` into.

    to `triggerAction`, or a combination:
     ```javascript

    An ArrayProxy wraps any other object that implements `Ember.Array` and/or
    `Ember.MutableArray,` forwarding all requests. This makes it very useful for
    a number of binding use cases or other cases where being able to swap
    out the underlying array is useful.
  
    A simple example of usage:
  
    ```javascript
    var pets = ['dog', 'cat', 'fish'];
    var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
  
    ap.get('firstObject');                        // 'dog'
    ap.set('content', ['amoeba', 'paramecium']);
    ap.get('firstObject');                        // 'amoeba'
    ```
  
    This class can also be useful as a layer to transform the contents of
    an array, as they are accessed. This can be done by overriding
    `objectAtContent`:
  
    ```javascript
    var pets = ['dog', 'cat', 'fish'];
    var ap = Ember.ArrayProxy.create({
        content: Ember.A(pets),
        objectAtContent: function(idx) {
            return this.get('content').objectAt(idx).toUpperCase();
        }
    });
  
    ap.get('firstObject'); // . 'DOG'

      Creates a new subclass.
       ```javascript
      App.Person = Ember.Object.extend({
        say: function(thing) {
          alert(thing);
         }
      });
      ```
       This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
       You can also create a subclass from any existing class by calling its `extend()` method.
      For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
       ```javascript
      App.PersonView = Ember.View.extend({
        tagName: 'li',
        classNameBindings: ['isAdministrator']
      });
      ```
       When defining a subclass, you can override methods but still access the
      implementation of your parent class by calling the special `_super()` method:
       ```javascript
      App.Person = Ember.Object.extend({
        say: function(thing) {
          var name = this.get('name');
          alert(name + ' says: ' + thing);
        }
      });
       App.Soldier = App.Person.extend({
        say: function(thing) {
          this._super(thing + ", sir!");
        },
        march: function(numberOfHours) {
          alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.');
        }
      });
       var yehuda = App.Soldier.create({
        name: "Yehuda Katz"
      });
       yehuda.say("Yes");  // alerts "Yehuda Katz says: Yes, sir!"
      ```
       The `create()` on line #17 creates an *instance* of the `App.Soldier` class.
      The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance
      of the `App.Person` class will *not* have the `march()` method.
       You can also pass `Mixin` classes to add additional properties to the subclass.
       ```javascript
      App.Person = Ember.Object.extend({
        say: function(thing) {
          alert(this.get('name') + ' says: ' + thing);
        }
      });
       App.SingingMixin = Mixin.create({
        sing: function(thing){
          alert(this.get('name') + ' sings: la la la ' + thing);
        }
      });
       App.BroadwayStar = App.Person.extend(App.SingingMixin, {
        dance: function() {
          alert(this.get('name') + ' dances: tap tap tap tap ');
        }
      });
      ```
       The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.
       @method extend
      @static
       @param {Mixin} [mixins]* One or more Mixin classes

       `create` will call the `init` function if defined during

/**
  Defines the properties that will be concatenated from the superclass
  (instead of overridden).
   By default, when you extend an Ember class a property defined in
  the subclass overrides a property with the same name that is defined
  in the superclass. However, there are some cases where it is preferable
  to build up a property's value by combining the superclass' property
  value with the subclass' value. An example of this in use within Ember
  is the `classNames` property of `Ember.View`.
   Here is some sample code showing the difference between a concatenated
  property and a normal one:
   ```javascript
  App.BarView = Ember.View.extend({
    someNonConcatenatedProperty: ['bar'],
    classNames: ['bar']
  });
   App.FooBarView = App.BarView.extend({
    someNonConcatenatedProperty: ['foo'],
    classNames: ['foo']
  });
   var fooBarView = App.FooBarView.create();
  fooBarView.get('someNonConcatenatedProperty'); // ['foo']
  fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
  ```
   This behavior extends to object creation as well. Continuing the
  above example:
   ```javascript
  var view = App.FooBarView.create({
    someNonConcatenatedProperty: ['baz'],
    classNames: ['baz']
  })
  view.get('someNonConcatenatedProperty'); // ['baz']
  view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
  ```
  Adding a single property that is not an array will just add it in the array:
   ```javascript
  var view = App.FooBarView.create({
    classNames: 'baz'
  })
  view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
  ```
   Using the `concatenatedProperties` property, we can tell Ember to mix the
  content of the properties.
   In `Ember.View` the `classNameBindings` and `attributeBindings` properties
  are also concatenated, in addition to `classNames`.
   This feature is available for you to use throughout the Ember object model,
  although typical app developers are likely to use it infrequently. Since
  it changes expectations about behavior of properties, you should properly
  document its usage in each individual concatenated property (to not
  mislead your users to think they can override the property in a subclass).

/**
  Defines the properties that will be merged from the superclass
  (instead of overridden).
   By default, when you extend an Ember class a property defined in
  the subclass overrides a property with the same name that is defined
  in the superclass. However, there are some cases where it is preferable
  to build up a property's value by merging the superclass property value
  with the subclass property's value. An example of this in use within Ember
  is the `queryParams` property of routes.
   Here is some sample code showing the difference between a merged
  property and a normal one:
   ```javascript
  App.BarRoute = Ember.Route.extend({
    someNonMergedProperty: {
      nonMerged: 'superclass value of nonMerged'
    },
    queryParams: {
      page: {replace: false},
      limit: {replace: true}
    }
  });
   App.FooBarRoute = App.BarRoute.extend({
    someNonMergedProperty: {
      completelyNonMerged: 'subclass value of nonMerged'
    },
    queryParams: {
      limit: {replace: false}
    }
  });
   var fooBarRoute = App.FooBarRoute.create();
   fooBarRoute.get('someNonMergedProperty');
  // => { completelyNonMerged: 'subclass value of nonMerged' }
  //
  // Note the entire object, including the nonMerged property of
  // the superclass object, has been replaced
   fooBarRoute.get('queryParams');
  // => {
  //   page: {replace: false},
  //   limit: {replace: false}
  // }
  //
  // Note the page remains from the superclass, and the
  // `limit` property's value of `false` has been merged from
  // the subclass.
  ```
   This behavior is not available during object `create` calls. It is only
  available at `extend` time.
   This feature is available for you to use throughout the Ember object model,
  although typical app developers are likely to use it infrequently. Since

    `RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
    a fail-fast method, it waits until all the promises have returned and
    shows you all the results. This is useful if you want to handle multiple
    promises' failure states together as a set.
  
    Returns a promise that is fulfilled when all the given promises have been
    settled. The return promise is fulfilled with an array of the states of
    the promises passed into the `promises` array argument.
  
    Each state object will either indicate fulfillment or rejection, and
    provide the corresponding value or reason. The states will take one of
    the following formats:
  
    ```javascript
    { state: 'fulfilled', value: value }
      or
    { state: 'rejected', reason: reason }
    ```
  
    Example:
  
    ```javascript
    var promise1 = RSVP.Promise.resolve(1);
    var promise2 = RSVP.Promise.reject(new Error('2'));
    var promise3 = RSVP.Promise.reject(new Error('3'));
    var promises = [ promise1, promise2, promise3 ];
  
    RSVP.allSettled(promises).then(function(array){
      // array == [
      //   { state: 'fulfilled', value: 1 },
      //   { state: 'rejected', reason: Error },
      //   { state: 'rejected', reason: Error }
      // ]
      // Note that for the second item, reason.message will be '2', and for the
      // third item, reason.message will be '3'.
    }, function(error) {
      // Not run. (This block would only be called if allSettled had failed,
      // for instance if passed an incorrect argument type.)

  /**
    `RSVP.hashSettled` is similar to `RSVP.allSettled`, but takes an object
    instead of an array for its `promises` argument.
  
    Unlike `RSVP.all` or `RSVP.hash`, which implement a fail-fast method,
    but like `RSVP.allSettled`, `hashSettled` waits until all the
    constituent promises have returned and then shows you all the results
    with their states and values/reasons. This is useful if you want to
    handle multiple promises' failure states together as a set.
  
    Returns a promise that is fulfilled when all the given promises have been
    settled, or rejected if the passed parameters are invalid.
  
    The returned promise is fulfilled with a hash that has the same key names as
    the `promises` object argument. If any of the values in the object are not
    promises, they will be copied over to the fulfilled object and marked with state
    'fulfilled'.
  
    Example:
  
    ```javascript
    var promises = {
      myPromise: RSVP.Promise.resolve(1),
      yourPromise: RSVP.Promise.resolve(2),
      theirPromise: RSVP.Promise.resolve(3),
      notAPromise: 4
    };
  
    RSVP.hashSettled(promises).then(function(hash){
      // hash here is an object that looks like:
      // {
      //   myPromise: { state: 'fulfilled', value: 1 },
      //   yourPromise: { state: 'fulfilled', value: 2 },
      //   theirPromise: { state: 'fulfilled', value: 3 },
      //   notAPromise: { state: 'fulfilled', value: 4 }
      // }
    });
    ```
  
    If any of the `promises` given to `RSVP.hash` are rejected, the state will
    be set to 'rejected' and the reason for rejection provided.
  
    Example:
  
    ```javascript
    var promises = {
      myPromise: RSVP.Promise.resolve(1),
      rejectedPromise: RSVP.Promise.reject(new Error('rejection')),
      anotherRejectedPromise: RSVP.Promise.reject(new Error('more rejection')),
    };
  
    RSVP.hashSettled(promises).then(function(hash){
      // hash here is an object that looks like:
      // {
      //   myPromise:              { state: 'fulfilled', value: 1 },
      //   rejectedPromise:        { state: 'rejected', reason: Error },
      //   anotherRejectedPromise: { state: 'rejected', reason: Error },
      // }
      // Note that for rejectedPromise, reason.message == 'rejection',
      // and for anotherRejectedPromise, reason.message == 'more rejection'.
    });
    ```
  
    An important note: `RSVP.hashSettled` is intended for plain JavaScript objects that
    are just a set of keys and values. `RSVP.hashSettled` will NOT preserve prototype
    chains.
  
    Example:
  
    ```javascript
    function MyConstructor(){
      this.example = RSVP.Promise.resolve('Example');
    }
  
    MyConstructor.prototype = {
      protoProperty: RSVP.Promise.resolve('Proto Property')
    };
  
    var myObject = new MyConstructor();

      // }

  /**
    `RSVP.denodeify` takes a 'node-style' function and returns a function that
    will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
    browser when you'd prefer to use promises over using callbacks. For example,
    `denodeify` transforms the following:
  
    ```javascript
    var fs = require('fs');
  
    fs.readFile('myfile.txt', function(err, data){
      if (err) return handleError(err);
      handleData(data);
    });
    ```
  
    into:
  
    ```javascript
    var fs = require('fs');
    var readFile = RSVP.denodeify(fs.readFile);
  
    readFile('myfile.txt').then(handleData, handleError);
    ```
  
    If the node function has multiple success parameters, then `denodeify`
    just returns the first one:
  
    ```javascript
    var request = RSVP.denodeify(require('request'));
  
    request('http://example.com').then(function(res) {
      // ...
    });
    ```
  
    However, if you need all success parameters, setting `denodeify`'s
    second parameter to `true` causes it to return all success parameters
    as an array:
  
    ```javascript
    var request = RSVP.denodeify(require('request'), true);
  
    request('http://example.com').then(function(result) {
      // result[0] -> res
      // result[1] -> body
    });
    ```
  
    Or if you pass it an array with names it returns the parameters as a hash:
  
    ```javascript
    var request = RSVP.denodeify(require('request'), ['res', 'body']);
  
    request('http://example.com').then(function(result) {
      // result.res
      // result.body
    });
    ```
  
    Sometimes you need to retain the `this`:
  
    ```javascript
    var app = require('express')();
    var render = RSVP.denodeify(app.render.bind(app));
    ```
  
    The denodified function inherits from the original function. It works in all
    environments, except IE 10 and below. Consequently all properties of the original
    function are available to you. However, any properties you change on the
    denodeified function won't be changed on the original function. Example:
  
    ```javascript
    var request = RSVP.denodeify(require('request')),
        cookieJar = request.jar(); // <- Inheritance is used here
  
    request('http://example.com', {jar: cookieJar}).then(function(res) {
      // cookieJar.cookies holds now the cookies returned by example.com
    });
    ```
  
    Using `denodeify` makes it easier to compose asynchronous operations instead
    of using callbacks. For example, instead of:
  
    ```javascript
    var fs = require('fs');
  
    fs.readFile('myfile.txt', function(err, data){
      if (err) { ... } // Handle error
      fs.writeFile('myfile2.txt', data, function(err){
        if (err) { ... } // Handle error
        console.log('done')
      });
    });
    ```
  
    you can chain the operations together using `then` from the returned promise:
  
    ```javascript
    var fs = require('fs');
    var readFile = RSVP.denodeify(fs.readFile);
    var writeFile = RSVP.denodeify(fs.writeFile);
  
    readFile('myfile.txt').then(function(data){
      return writeFile('myfile2.txt', data);
    }).then(function(){
      console.log('done')
    }).catch(function(error){
      // Handle error
    });
    ```

    elements of the passed iterable to promises as it runs this algorithm.

    `RSVP.Promise.race` is deterministic in that only the state of the first
    settled promise matters. For example, even if other promises given to the

    become rejected before the other promises became fulfilled, the returned
    promise will become rejected:
  
    ```javascript

  /**
    Promise objects represent the eventual result of an asynchronous operation. The
    primary way of interacting with a promise is through its `then` method, which
    registers callbacks to receive either a promise’s eventual value or the reason
    why the promise cannot be fulfilled.
  
    Terminology
    -----------
  
    - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
    - `thenable` is an object or function that defines a `then` method.
    - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
    - `exception` is a value that is thrown using the throw statement.
    - `reason` is a value that indicates why a promise was rejected.
    - `settled` the final resting state of a promise, fulfilled or rejected.
  
    A promise can be in one of three states: pending, fulfilled, or rejected.
  
    Promises that are fulfilled have a fulfillment value and are in the fulfilled
    state.  Promises that are rejected have a rejection reason and are in the
    rejected state.  A fulfillment value is never a thenable.
  
    Promises can also be said to *resolve* a value.  If this value is also a
    promise, then the original promise's settled state will match the value's
    settled state.  So a promise that *resolves* a promise that rejects will
    itself reject, and a promise that *resolves* a promise that fulfills will
    itself fulfill.
  
  
    Basic Usage:
    ------------
  
    ```js
    var promise = new Promise(function(resolve, reject) {
      // on success
      resolve(value);
  
      // on failure
      reject(reason);
    });
  
    promise.then(function(value) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Advanced Usage:
    ---------------
  
    Promises shine when abstracting away asynchronous interactions such as
    `XMLHttpRequest`s.
  
    ```js
    function getJSON(url) {
      return new Promise(function(resolve, reject){
        var xhr = new XMLHttpRequest();
  
        xhr.open('GET', url);
        xhr.onreadystatechange = handler;
        xhr.responseType = 'json';
        xhr.setRequestHeader('Accept', 'application/json');

    /**
      The primary way of interacting with a promise is through its `then` method,
      which registers callbacks to receive either a promise's eventual value or the
      reason why the promise cannot be fulfilled.
    
      ```js
      findUser().then(function(user){
        // user is available
      }, function(reason){
        // user is unavailable, and you are given the reason why
      });
      ```
    
      Chaining
      --------
    
      The return value of `then` is itself a promise.  This second, 'downstream'
      promise is resolved with the return value of the first promise's fulfillment
      or rejection handler, or rejected if the handler throws an exception.
    
      ```js
      findUser().then(function (user) {
        return user.name;
      }, function (reason) {
        return 'default name';
      }).then(function (userName) {
        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
        // will be `'default name'`
      });
    
      findUser().then(function (user) {
        throw new Error('Found user, but still unhappy');
      }, function (reason) {
        throw new Error('`findUser` rejected and we're unhappy');
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
      });
      ```
      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
    
      ```js
      findUser().then(function (user) {
        throw new PedagogicalException('Upstream error');
      }).then(function (value) {
        // never reached
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // The `PedgagocialException` is propagated all the way down to here
      });
      ```
    
      Assimilation
      ------------
    
      Sometimes the value you want to propagate to a downstream promise can only be
      retrieved asynchronously. This can be achieved by returning a promise in the
      fulfillment or rejection handler. The downstream promise will then be pending
      until the returned promise is settled. This is called *assimilation*.
    
      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // The user's comments are now available
      });
      ```
    
      If the assimliated promise rejects, then the downstream promise will also reject.
    
      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // If `findCommentsByAuthor` fulfills, we'll have the value here
      }, function (reason) {
        // If `findCommentsByAuthor` rejects, we'll have the reason here
      });
      ```

    `RSVP.rethrow` will rethrow an error on the next turn of the JavaScript event
    loop in order to aid debugging.
  
    Promises A+ specifies that any exceptions that occur with a promise must be
    caught by the promises implementation and bubbled to the last handler. For
    this reason, it is recommended that you always specify a second rejection
    handler function to `then`. However, `RSVP.rethrow` will throw the exception
    outside of the promise, so it bubbles up to your console if in the browser,
    or domain/cause uncaught exception in Node. `rethrow` will also throw the
    error again so the error can be handled by the promise per the spec.
  
    ```javascript
    function throws(){
      throw new Error('Whoops!');
    }
  
    var promise = new RSVP.Promise(function(resolve, reject){
      throws();
    });
  
    promise.catch(RSVP.rethrow).then(function(){
      // Code here doesn't run because the promise became rejected due to an
      // error!
    }, function (err){
      // handle the error here
    });
    ```
  
    The 'Whoops' error will be thrown on the next turn of the event loop
    and you can watch for it in your console. You can also handle it using a
    rejection handler given to `.then` or `.catch` on the returned promise.
