这个文件分为几个部分
1、定义系统常量和server常量
2、定义ecmall类，加载从入口文件中配置的类库和控制器以及模型类库
3、请求转发，如果定义了默认的路由，以此转发，如果没有定义默认控制器为 default 和index
4、从参数app和action中获取控制器和动作
5、更具配置参数中的路径和 $_REQUEST中获取的controller name 加载控制器，如果没有找到抛出异常
6、加载控制器 define('APP', $app); define('ACT', $act); 定义两个常量
7、转发到相关的action do_action()
另外需要说明的就是在 ecmall.php中定义了系统中所有的基类
8、使用v()方法初始化模板引擎对象_init_view()
9、assign方法把变量带如模板
10、display()输出。
视图层的细节和model类的细节等下再来研究
