Ancient Game of Nimm

"""
The game of Nimm goes as follows:
+ The game starts with a pile of 20 stones between the players.
+ The two players alternate turns.
+ On a given turn, a player may take either 1 or 2 stone from the center pile.
+ The two players continue until the center pile has run out of stones.
+ The last player to take a stone loses.
