/**

 *     综合练习————洗牌发牌Easy版

 * 功能描述：

 * 1、创建一副扑克牌 

 * 包括四种花色：黑桃、红桃、梅花、方片

 * 十三种点数：2-10，J,Q,K,A,不考虑大小王

 * 2、创建两名玩家

 * 玩家至少有ID、姓名、手牌等属性，手牌为扑克牌的集合

 * 3、洗牌

 * 将之前创建的“一副扑克牌”打乱顺序

 * 4、发牌

 * 将洗牌之后的扑克牌集合，从第一张开始,发给两名玩家，

 * 按照一人一张的方式，每人发两张

 * 5、游戏

 * 比较两名玩家手中的扑克牌，规则为：取两人各自手中点数最大的牌进行比较，

 * 点数大的赢；若两人各自的点数最大的牌相等，则再按花色比较
