----- The following code has been added to Card.java ----

  /** This constructor would be useful when we want to shuffle cards,
   *  because a random number generator can give us a number 1-52.
   *  We assume that our parameter i is in the range 1-52.
   *  Because of the behavior of the % and / operators,
   *  the denom number will be:  1=ace, 2=two, ..., 12=queen, 0=king
   *  and the suit number will be 0=clubs up to 3=spades.
   *  We need to say (i-1) for calculating the suit number because
   *  we want the outcome to be in the range 0-3, and the king of spades,
   *  being card # 52, would have been 52/13 = 4.  The other kings would have
   *  been wrong too:  13 (king of clubs) would have been called a diamond.
