使用方法：把上面的代码另存为MY_Router.php,放在你应用目录的core目录下。假设你的应用放在application目录,哪么你把MY_Router.php文件放在application/core目录下即可：

原生的CI最多只支持一级目录,地址如下：controllers/directory/appname.php,现在你可以写成controllers/directory/directory/directory/appname.php,如果你不觉得累写多少都没关系 (^0^)。

现目前在Codeigniter 2.1.0、Codeigniter 2.1.1、Codeigniter 2.1.2都测试通过！
