/* <?zy jQuery第一版注解
* 作者 cloud2han9.net ?>
*
* 概述：
* jQuery源码主要分为
* - 入口函数jQuery或者$
* - 原型函数jQuery.prototype
* - 扩展函数jQuery.extend
* - 宏jQuery.macros
*
* 除了入口函数，所有函数都在jQuery.fn名字空间，
* 这里面是我们使用jQuery时可以使用的函数。
*
* 宏 表面上是一个对象， 其实jQuery.init会把他们转化
* 为jQuery名字空间里的函数。宏和jQuery.init定义了jQuery函数到
* DOM函数的一个转换。
