/**
 * <code>YUI</code>'s <code>on</code> method is a unified interface for subscribing to
 * most events exposed by YUI.  This includes custom events, DOM events, and 
 * function events.  <code>detach</code> is also provided to remove listeners
 * serviced by this function.
 *
 * The signature that <code>on</code> accepts varies depending on the type
 * of event being consumed.  Refer to the specific methods that will
 * service a specific request for additional information about subscribing
 * to that type of event.
 *
 * <ul>
 * <li>Custom events.  These events are defined by various
 * modules in the library.  This type of event is delegated to
 * <code>EventTarget</code>'s <code>on</code> method.
 *   <ul>
 *     <li>The type of the event</li>
 *     <li>The callback to execute</li>
 *     <li>An optional context object</li>
 *     <li>0..n additional arguments to supply the callback.</li>
 *   </ul>
 *   Example: 
 *   <code>Y.on('drag:drophit', function() { // start work });</code>
 * </li>
 * <li>DOM events.  These are moments reported by the browser related
 * to browser functionality and user interaction.
 * This type of event is delegated to <code>Event</code>'s 
 * <code>attach</code> method.
 *   <ul>
 *     <li>The type of the event</li>
 *     <li>The callback to execute</li>
 *     <li>The specification for the Node(s) to attach the listener
 *     to.  This can be a selector, collections, or Node/Element
 *     refereces.</li>
 *     <li>An optional context object</li>
 *     <li>0..n additional arguments to supply the callback.</li>
 *   </ul>
 *   Example: 
 *   <code>Y.on('click', function(e) { // something was clicked }, '#someelement');</code>
 * </li>
 * <li>Function events.  These events can be used to react before or after a
 * function is executed.  This type of event is delegated to <code>Event.Do</code>'s 
 * <code>before</code> method.
 *   <ul>
 *     <li>The callback to execute</li>
 *     <li>The object that has the function that will be listened for.</li>
 *     <li>The name of the function to listen for.</li>
 *     <li>An optional context object</li>
 *     <li>0..n additional arguments to supply the callback.</li>
 *   </ul>
 *   Example <code>Y.on(function(arg1, arg2, etc) { // obj.methodname was executed }, obj 'methodname');</code>
 * </li>
 * </ul>
 *
 * <code>on</code> corresponds to the moment before any default behavior of
 * the event.  <code>after</code> works the same way, but these listeners
 * execute after the event's default behavior.  <code>before</code> is an
 * alias for <code>on</code>.
 *
 * @method on 
 * @param type event type (this parameter does not apply for function events)
 * @param fn the callback
 * @param context optionally change the value of 'this' in the callback
 * @param args* 0..n additional arguments to pass to the callback.

    *      transport instead of XMLHttpRequest.
    *      The properties are:
    *      {
    *        use: Specify the transport to be used: 'flash' and 'native'
    *        dataType: Set the value to 'XML' if that is the expected
    *                  response content type.
    *      }
    *
    *
    * form: This is a defined object used to process HTML form as data.  The
    *       properties are:
    *       {
    *         id: Node object or id of HTML form.
    *         useDisabled: Boolean value to allow disabled HTML form field
    *                      values to be sent as part of the data.
    *       }
    *
    * on: This is a defined object used to create and handle specific
    *     events during a transaction lifecycle.  These events will fire in
    *     addition to the global io events. The events are:
    *     start - This event is fired when a request is sent to a resource.
    *     complete - This event fires when the transaction is complete.
    *     success - This event fires when the response status resolves to
    *               HTTP 2xx.
    *     failure - This event fires when the response status resolves to
    *               HTTP 4xx, 5xx; and, for all transaction exceptions,
    *               including aborted transactions and transaction timeouts.
    *     end -  This even is fired at the conclusion of the transaction
    *            lifecycle, after a success or failure resolution.
    *
    *     The properties are:
    *     {
    *       start: function(id, arguments){},
    *       complete: function(id, responseobject, arguments){},
    *       success: function(id, responseobject, arguments){},
    *       failure: function(id, responseobject, arguments){},
    *       end: function(id, arguments){}
    *     }
    *     Each property can reference a function or be written as an
    *     inline function.
    *
    * sync: To enable synchronous transactions, set the configuration property
    *       "sync" to true; the default behavior is false.  Synchronous
    *       transactions are limited to same-domain requests only.
    *
    * context: Object reference for all defined transaction event handlers
    *          when it is implemented as a method of a base object. Defining
    *          "context" will set the reference of "this," used in the
    *          event handlers, to the context value.  In the case where
    *          different event handlers all have different contexts,
    *          use Y.bind() to set the execution context, bypassing this
    *          configuration.
    *
    * headers: This is a defined object of client headers, as many as.
    *          desired for the transaction.  The object pattern is:
    *          { 'header': 'value' }.
    *
    * timeout: This value, defined as milliseconds, is a time threshold for the
    *          transaction. When this threshold is reached, and the transaction's
    *          Complete event has not yet fired, the transaction will be aborted.
    *
    * arguments: Object, array, string, or number passed to all registered
    *            event handlers.  This value is available as the second
    *            argument in the "start" and "abort" event handlers; and, it is
    *            the third argument in the "complete", "success", and "failure"
    *            event handlers.
