EventManager是一个非常有用的第三方类, 使用hash表实现了面向实例的事件管理. 最终实现的removeAllListener方法对需要管理大量事件监听器的程序来说是个福音吧.

This class keeps track of listeners being used. This class is VERY useful in development and is HIGHLY recommended to be used.
Instead of MyObj.addEventListener(Event.ENTER_FRAME, someFunction, false, 0, true)
do: EventManager.addEventListener(MyObj,Event.ENTER_FRAME, someFunction);
