      A simple implementation of Blackjack: Deck with unlimited cards.
  
      The objective of the game is beat the dealer closer to 21 without going over.
      Cards between 2 - 10 inclusive are worth pip value; J, Q, and K are worth 10.
      The Ace could be worth 1 or 11, the holder of the card determines the value.
  
      The rewards are:
  
      -1 if the player loses
      0 if its a stand
      1 if the player wins
  
      The actions at each stage are either hit or stand.
      Hit retrieves an additional card, while stand terminates the move.
