 @Name：layui.treeGrid 树表格操作
 @Author：luonianqing
 @License：public,
 首先感谢Layui的原码分项,本源码是在table.js的基面上改进的,如有BUG,请直接在FLY上留言,代码存在冗余,因为看得不够细,没时间,项目需要,Layui没有,我就写了
 去除了排序,因为树型不支持表头排序
 去除了全选,因为没有意义,不支持分页,因为也没有意义,也支除了记录条数限制,下级分支有多少条就展示多少条,只支持动态数据,不支持静态
 增加了行选功能.即只要单击,其它的全不选,只有结点会被选中,
 增加了treeDataCache,因为树是多级目录关系
 不支持,树枝选择,下面全部被选中,也许将来会支持,现在满足项目需求即可,新增了注代码
