根据GB2312汉字区位码获取汉字拼音的工具类
申明：
本工具类的原型来自互联网，本人作了算法上的调整。所以严格上不算原创，只能算是编著。
主要思路：
根据gb2312汉字的区位码，建立区位码与拼音的对应关系，因为一定范围内的汉字区位码的拼音是一样的，例如，如果汉字的区位码在(20317,20319]范围内，那么其拼音为“a”。
所以本工具类首先建立连个数组，一个边界放区位码，何谓边界区位码，如20317与20318两个区位码相连续，但是其对应的拼音一个是“ai”，一个是“a”，不连续，那么20317就是边界区位码；一个数组存放边界区位码对应的拼音，利用边界区位码作为数组的索引，对应的拼音为值。
对于给定的汉字，首先计算器区位码，而后根据取上不取下的原则找到其拼音对应的边界区位码，如一个汉字的区位码是20318，那么20318两端的边界区位码一个是20317，一个是20319，根据取上不取下原则，获得20318对应的区位码拼音的边界区位码20319，根据20319获得20318的拼音为“a”。
缺点：字符集不大，仅限于gb312；多音字只对应一个音，如“银行”，“行走”中的“行”字的拼音是一样的，所以如果外部输入都是汉字，由本工具转换为拼音去查同音，没有问题，如果外部输入拼音，就有问题。
