    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(name, timestamp, payload) {
  
      },
  
      after(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
    added to other classes. For instance,
  
    ```javascript
    const EditableMixin = Ember.Mixin.create({
      edit() {
        console.log('starting to edit');
        this.set('isEditing', true);
      },

    // `.extend.`
    const Comment = Ember.Object.extend(EditableMixin, {
      post: null
    });
  
    let comment = Comment.create({
      post: somePost
    });
  
    comment.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
    const FilterableMixin = Ember.Mixin.create({
      filters: Ember.A()
    });
  
    // filters will be a separate array for every object implementing the mixin
    const FilterableMixin = Ember.Mixin.create({
      filters: Ember.computed(function() {
        return Ember.A();
      })
    });
  
    // filters will be created as a separate array during the object's initialization
    const Filterable = Ember.Mixin.create({
      init() {
        this._super(...arguments);
        this.set("filters", Ember.A());

    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.
  
    ## Examples
  
    ```javascript
    // ES5 compatible mode
    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.

    Allows you to specify which context to call the specified function in while
    adding the execution of that function to the Ember run loop. This ability
    makes this method a great way to asynchronously integrate third-party libraries
    into your Ember application.
  
    `run.bind` takes two main arguments, the desired context and the function to
    invoke in that context. Any additional arguments will be supplied as arguments
    to the function that is passed in.
  
    Let's use the creation of a TinyMCE component as an example. Currently,
    TinyMCE provides a setup configuration option we can use to do some processing
    after the TinyMCE instance is initialized but before it is actually rendered.
    We can use that setup option to do some additional setup for our component.
    The component itself could look something like the following:
  
    ```javascript
    App.RichTextEditorComponent = Ember.Component.extend({
      initializeTinyMCE: Ember.on('didInsertElement', function() {
        tinymce.init({
          selector: '#' + this.$().prop('id'),
          setup: Ember.run.bind(this, this.setupEditor)
        });
      }),
  
      setupEditor: function(editor) {
        this.set('editor', editor);
  
        editor.on('change', function() {
          console.log('content changed!');
        });
      }
    });
    ```
  
    In this example, we use Ember.run.bind to bind the setupEditor method to the
    context of the App.RichTextEditorComponent and to have the invocation of that
    method be safely handled and executed by the Ember run loop.
  
    @method bind

    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).

    ```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

    happen once scrolling has ceased.

  /**
    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.
  
    Some numbers: http://jsperf.com/eval-vs-keys/8
