/*Beetle游戏的java实现
  作者：viMory
  时间：2008.5.3
  游戏规则：参与人数1人以上，谁的甲虫最先完整谁就胜出。初始的甲虫不具有任何器官，而完整的甲虫具有躯干、头部、6条腿、两只眼、两只触角、一条尾巴。 
玩法：轮你掷骰子时，按如下规定采取动作： 
1：如果甲虫已有一处躯干，传骰子给下一位。否则，添加一个躯干，并再掷一次。 
2：如果甲虫已有头部或没有躯干，传骰子。否则，添加一个头部，并再掷一次。 
3：如果甲虫已有6条腿或没有躯干，传骰子，否则，添加两条腿，并再掷一次。 
4：如果甲虫已有两只眼或没有头部，传骰子。否则，添加一只眼睛，并再掷一次。 
5：如果甲虫已有两根触角或没有头部，传骰子，否则，添加一根触角，并再掷一次。 
6：如果甲虫已有一条尾巴或没有躯干，传骰子。否则，添加一条尾巴，并再掷一次。
