/* computer player is an extension of the player class that will automatically
   play its turns.  The too long function, ChoosePlay, attempts to play
   from the store stack, then from the hand, then from a discard stack, and 
   then finally if plays from the hand to a discard stack to end its turn.
   Any successful play to the build stacks (either from the hand, store, or
   discard stack) will return a value of true indicating that the computer
   player will continue.  Any play from the hand to a discard stack will 
   return false indicating that the turn is over. */
