 Description: WAR is a card game that pits two players against each other. The deck is shuffled and then each player 
              is given half the deck. On each turn, each player draws a card and faces them against each other.
	      The card with the higher value wins the round with ace being one, jack being 11, queen being 12 and king being 13.
	      The player that has the most rounds won, wins!
