Monster Card Game的设计与实现之服务器篇

服务器端大概有这么几个类：

MonsterCard类：定义卡牌的属性

Deck类：用来生产一堆卡牌，在这个游戏中共40张怪兽卡牌。

Player类：用来定义一个玩家，这个玩家具有40张怪兽卡牌和8000滴血，然后根据玩家的对战情况进行减少卡牌或扣除学的操作。

MyServerReader类：建立一个线程，根据对方玩家发来的的命令来对自己或对方玩家的怪兽卡牌进行操作

MyServerWriter类：建立一个线程，根据自己发出的的命令来对自己或对方玩家的怪兽卡牌进行操作

ServerTest类：负责和客户端进行通信，共享玩家的数据。
