This program plays a takeaway game. the players who are playing are asked to
name themselves and input the amount of rounds they would like to play (between 1 and 5)
and then the game starts

This program asks the players to take 1-3 chips from a total of 21 chips. 
The player that wins the round is the one who takes the last chip from the pile leaving 0 chips remaining.
