nimgame

代码说明：

尼姆游戏，java实现，玩家信息操作，进行游戏，分为三个java文件。In this project, we introduce a third class NimGame. The game playing process is delegated from Nimsys to NimGame. Since only one game will be active at any given time, only a single NimGame instance is required by Nimsys. Nimsys should also maintain a collection of players. Initially, this collection will be empty - players will need to be added in order to play a game.
