    /* Here is where I'm very confused:
      The assignment was to have the game allow the user and computer to pick again,
      but I cannot, for the life of me, figure our how to do it.  At this point in the tutorials, 
      we have only used if/else if/else statements.
      
      I tried:
    	
    	return choice1 = prompt ("It's a tie guess again!")
    	
    	  But that just created an infinite loop.  Should I create another function within
          a function, or is there a way to just tell the original function to run again?
