/* 
   An object belonging to the class Card represents a playing card.
   with a suit (clubs, hearts, spades, or diamonds) and a value (ace,
   jack, queen, king, or one of the numbers 2 thrugh 10).  The
   suit is represented by an integer between 0 and 3, and the value
   is represented by an integer between 0 and 12.  Note that, unfortunately,
   the value of an ACE is 0, the value of a TWO is 1, etc.
