Card Sorter game
    
    Java Swing card sorter game.  Watch the video demo.
    
    Seven random cards from a standard deck are initially displayed in
    the top panel.  (The same card may appear more than
    once.)   When a card is clicked in the top panel, it is
    moved to the right end of the cards in the lower panel. If the card
    is out of order, an error message popup dialog appears.  If all
    seven cards are placed in order, a win message appears. 
    
    The correct order is by suit, then rank.  Hearts, Clubs,
    Diamonds, Spades.
    
    The status panel displays a Help button, a Try Again button, and the
    count of won and lost games.   
    
    You may use these public
      domain card images (zip). 
    
    Here is a skeleton of the
      application.   You may add helper methods if you
    like.  You may define other classes (like a Card class).
