/**
 * wind路由基础实现
 * 
 * 该路由是框架默认路由实现继承自{@see AbstractWindRouter},
 * 'WindRouter'是利用路由链机制实现了多路由协议支持.在没有任何路由协议定义的情况下,直接进行参数解析.
 * 路由的使用方式举例:<code>
 * //路由支持的配置如下:
 * 'module' => array(	//module相关配置
 * 'url-param' => 'm',
 * 'default-value' => 'default',
 * ),
 * 'controller' => array(	//controller相关配置
 * 'url-param' => 'c',
 * 'default-value' => 'index',
 * ),
 * 'action' => array(	//action相关配置
 * 'url-param' => 'a',
 * 'default-value' => 'run',
 * ),
 * //如果无需复杂的路由协议支持,或urlrewrite支持,无需配置下面下面信息
 * 'rules' => array(
 * 'WindRoute' => array(	//路由协议名称
 * 'class' => 'WIND:router.route.WindRoute',	//路由协议具体实现类
 * 'regex' => '',	//用于匹配的正则表达式
 * 'params' => array(),	//参数mapping
 * 'reverse' => '')),	//反向解析
 * </code>
