/*
*自动拆分复合词
*功能：将一个单词拆分为两个部分
*输入：想要拆的词
*输出：数组，第一个为前半部分，第二个为后半部分，前半部分是在现有字典里搜索到的。
*范例：
while(($split=mySplit($splitWord))!==FALSE){
	array_push($part,$split[0]);
	$splitWord=$split[1];
}
循环结束后$part里放的就是拆分结果

算法：从最后一个字母开始，一次去掉一个字母，然后在现有字典里搜索剩余的部分（前半部分）
如果搜索到，就返回。第二次，将剩余的部分，也就是后半部分应用相同的算法。
直到单词长度小于5
中间考虑了连音规则：
~a+i~=~i~
在拆分的时候要补上前面的元音
有时后面的词第一个辅音会重复
word+tha~=wordttha~
需要去掉后面的单词的一个辅音
