这个支持库文件源码,虽然没有什么功能，但代码书写整洁，不包含一条垃圾代码,而且注释非常清晰
大家可以从这个例子里领悟扩展它的功能,嘿嘿写出一个自己的支持库多有成就感,
写个什么辅助支持库啥的很不错哦！(This support library file source, although there is no function, but the code written neatly, does not contain a garbage code, and the notes are very clear

You can learn from this example, expand its function, hey, write a support library, a sense of accomplishment,

What to write an auxiliary support library, what is very good Oh!)
