//Event is a simple class for implementing the Observer pattern:
function Event(sender) {
this._sender = sender;
this._listeners = [];
}

Event.prototype = {
attach : function (listener) {//push the callback function into _listeners[];
this._listeners.push(listener);
},
notify : function (args) {//pop all the callback functions and execute the functions with same args?
var index;

for (index = 0; index < this._listeners.length; index += 1) {
this._listeners[index](this._sender, args);//auto pass sender and args into callback function, so the default form of callback function is function(sender,args){}
}
}
};
