Design and implement a Nim class and a NimGame application to allow two human players to play the game of Nim. The game starts with three piles of stones. The first pile has 3 stones, the second pile has 5 stones, and the last pile has 7 stones. The players take turns removing stones. On a single turn a player may only take stones from a single pile. A player may not take more than half the pile, except when it’s the last stone in the pile. The loser of the game is the player to take the very last stone.
