EventBus.js

/**
 * A MooTools implementation of an event bus to decouple
 * the event sender from the receiver. It is very similar to 
 * NSNotificationCenter in Cocoa.
 * 
 * MooTools Class.Extras already implements events. This class
 * acts as a tiny wrapper around the Class event system of MooTools
