/**
Augments the _receiver_ with prototype properties from the _supplier_. The
receiver may be a constructor function or an object. The supplier must be a
constructor function.

If the _receiver_ is an object, then the _supplier_ constructor will be called
immediately after _receiver_ is augmented, with _receiver_ as the `this` object.

If the _receiver_ is a constructor function, then all prototype methods of
_supplier_ that are copied to _receiver_ will be sequestered, and the
_supplier_ constructor will not be called immediately. The first time any
sequestered method is called on the _receiver_'s prototype, all sequestered
methods will be immediately copied to the _receiver_'s prototype, the
_supplier_'s constructor will be executed, and finally the newly unsequestered
method that was called will be executed.

This sequestering logic sounds like a bunch of complicated voodoo, but it makes
it cheap to perform frequent augmentation by ensuring that suppliers'
constructors are only called if a supplied method is actually used. If none of
the supplied methods is ever used, then there's no need to take the performance
hit of calling the _supplier_'s constructor.

@method augment
@param {Function|Object} receiver Object or function to be augmented.
@param {Function} supplier Function that supplies the prototype properties with
  which to augment the _receiver_.
@param {Boolean} [overwrite=false] If `true`, properties already on the receiver
  will be overwritten if found on the supplier's prototype.
@param {String[]} [whitelist] An array of property names. If specified,
  only the whitelisted prototype properties will be applied to the receiver, and
  all others will be ignored.
@param {Array|any} [args] Argument or array of arguments to pass to the
  supplier's constructor when initializing.
@return {Function} Augmented object.

`Y.on()` can do many things:

<ul>
    <li>Subscribe to custom events `publish`ed and `fire`d from Y</li>
    <li>Subscribe to custom events `publish`ed with `broadcast` 1 or 2 and
        `fire`d from any object in the YUI instance sandbox</li>
    <li>Subscribe to DOM events</li>
    <li>Subscribe to the execution of a method on any object, effectively
    treating that method as an event</li>
</ul>

For custom event subscriptions, pass the custom event name as the first argument and callback as the second. The `this` object in the callback will be `Y` unless an override is passed as the third argument.

    Y.on('io:complete', function () {
        Y.MyApp.updateStatus('Transaction complete');
    });

To subscribe to DOM events, pass the name of a DOM event as the first argument
and a CSS selector string as the third argument after the callback function.
Alternately, the third argument can be a `Node`, `NodeList`, `HTMLElement`,
array, or simply omitted (the default is the `window` object).

    Y.on('click', function (e) {
        e.preventDefault();

        // proceed with ajax form submission
        var url = this.get('action');
        ...
    }, '#my-form');

The `this` object in DOM event callbacks will be the `Node` targeted by the CSS
selector or other identifier.

`on()` subscribers for DOM events or custom events `publish`ed with a
`defaultFn` can prevent the default behavior with `e.preventDefault()` from the
event object passed as the first parameter to the subscription callback.

To subscribe to the execution of an object method, pass arguments corresponding to the call signature for 
<a href="../classes/Do.html#methods_before">`Y.Do.before(...)`</a>.

NOTE: The formal parameter list below is for events, not for function
injection.  See `Y.Do.before` for that signature.

    Subscribe a callback function for each `Node` in the collection to execute
    in response to a DOM event.

    NOTE: Generally, the `on()` method should be avoided on `NodeLists`, in
    favor of using event delegation from a parent Node.  See the Event user
    guide for details.

    Most DOM events are associated with a preventable default behavior, such as
    link clicks navigating to a new page.  Callbacks are passed a
    `DOMEventFacade` object as their first argument (usually called `e`) that
    can be used to prevent this default behavior with `e.preventDefault()`. See
    the `DOMEventFacade` API for all available properties and methods on the
    object.

    By default, the `this` object will be the `NodeList` that the subscription
    came from, <em>not the `Node` that received the event</em>.  Use
    `e.currentTarget` to refer to the `Node`.

    Returning `false` from a callback is supported as an alternative to calling
    `e.preventDefault(); e.stopPropagation();`.  However, it is recommended to
    use the event methods.

    @example

        Y.all(".sku").on("keydown", function (e) {
            if (e.keyCode === 13) {
                e.preventDefault();

                var item = Y.MyApp.searchInventory( e.currentTarget.get('value') );
