简化版的C++标准模板库，基于SGI STL
写这个东西的目的在于将庞大的STL简化为易读的数据结构、算法库
目前还未完成，为了方便编辑，所有文件都以.hpp为后缀而不是标准要求的无后缀名
A simplified C++ Standard Template Library based on SGI STL
C++ STL somtimes is too large and complex to learn. I build this simplified one to make it easyier and test my own algorithm design ability.
This project has not been finished yet and all files end with ".hpp" for convenient editing
