Now initializes a draw pile, completed some more of the infrastructure for deck and will add a shuffle method, added a quartets array to hands to and renamed hand class to player so that I can store the 4-of-a-kinds together for each player. The goal is to have 4 players. For now, 3 will be AIs and 1 will be a human. Also added a sortHand method to player class so all like-ranked cards will be adjacent (still haven't finished the implementation) and a draw method to the deck that will draw the next card from the draw pile.
