CodeIgniter Controller Bug修正
当 CodeIgniter 的 controller 名称和 model 或 library 的名称相同的时候，将产生错误。
以下修正了这个问题，从此可以为 controller, model, library 使用相同的 class name。
下载这个 MY_Router.php 并放到 application/libraries 文件夹即可
MY_Router.php

使用方法：
<?php
class UsersController extends Controller
{
public function __construct()
{
parent::__construct();
}
}
class UsersController extends Controller
{
public function __construct()
{
parent::__construct();
}
}
