match函数功能基本功能已经实现了！
但是感觉缺陷还是有很多的。
目前这个匹配功能还有一些不合理的地方（与算法有关的）
目前还没有解决的一些问题：匹配级别的更合理设定、半全角英文识别、未知出错bug（暂未发现但我觉得应该会有）。
接下来的两天的工作分别是TEST和优化。
TEST将有姚铭协助我进行（自己TEST自己好像很难。。）。
写一下函数模块吧：
match(string word,string keyword)//主函数
wordmatch(string w,string keyword)//word单个词对整个keyword匹配
wkmatch(string w,string k)//word单个词对整个keyword单个词匹配
//3种模糊程度函数
m3();
m2();
m1();
