老鼠出现引发的血案

老话题，委托、事件和方法，经典的案例，重新搞一下。

/*      老鼠出现引发的血案 ^_^
测试目标：老鼠出现后，猫叫，吓跑了老鼠且惊醒睡觉的主人，主人打猫，猫逃跑，老鼠乐了。
实现方法：先定义对象、再定义动作、再定义事件
实现理念：要事件驱动，关键事件MouseComeOut-老鼠出现、CatCry-猫叫、HitCat 主人打猫
 * Mouse :ComeOut()、Escape()动作；订阅Cat.Cry()-->Escape()
 * Cat：Cry()、Smile()、Escape()动作；订阅Mouse.ComeOut()-->Cry()
 * Man：Wakeup()、HitCat()动作；订阅Cat.Cry()-->Wakeup()
 *                                                                  -->HitCat()-->Cat.Escape()
结论：事件提供低耦合调用多个对象方法的特性;在使动者的方法内调用以引发事件！
