Start working on user interface
Implement UI to prompt for turn and discard a card
Bets now modify the pot
Raising now institutes another round of betting
Implement choosing a winner with the pot going to him, implement a play_game method that calls play_hand, deletes players if they have no bank left, and then keeps repeating until there is only one player
Add exception handling for when the deck is empty; shuffle the burn pile, set it to the deck, and make a new burn pile
