>     *  业务需求
>     *      斗地主的做牌，发牌，排序，看牌
>     *      业务，54张牌
>     *      点数："3","4","5","6","7","8","9","10","J","Q","K","A","2"
>     *      花色："♠","♥","♣","♦"
>     *      大小王："?"(大王)，"?‍?"(小王)
>     *      点数风暴要组合4种花色，大小王各一张
>     *      斗地主：发51张牌，剩下3张做底牌
>     *  功能：
>     *      1，做牌
>     *      2，洗牌
>     *      3，定义3个玩家
>     *      4，发牌
>     *      5，排序
>     *      6，看牌
>     *  面向对象设计案例
>     *      a,定义一个牌类，代表牌对象
>     *      b,定义一个集合存储54张牌，集合只需要1个
