/**
* class Jax.Helper
*
* Jax Helpers are glorified mixins. They contain a set of methods which can then be
* included into any Jax class.
*
* Defining a helper is easy, and looks a bit like this:
*
* var HelloHelper = Jax.Helper.create({
* sayHi: function(name) { alert("Hello, "+name+"!"); }
* });
*
* Once defined, using helpers is particularly simple. In any Jax class, simply define
* a +helpers+ function that returns an array of helpers:
*
* var Liaison = Jax.Class.create({
* helpers: function() { return [HelloHelper]; }
* });
*
* Now the +Liaison+ class will include the +sayHi+ method which can be called just like
* any other method:
*
* var l = new Liaison();
* l.sayHi("World");
* //=> Hello, World!
*
*
* As of Jax v1.1.0, you may also set the array of helpers directly on the +helpers+ property
* of a class, instead of defining a function. The following example is functionally
* equivalent to the above:
*
* var Liaison = Jax.Class.create({
* helpers: [HelloHelper]
* });
*
