 Exercise 11, chapter 10 of Zelle's "Intro Python"
 Jim Mahoney, Oct 30 2006

 The test at the bottom (printing some random cards)
 happen if this is run from the command line,
 either with 'python play_card.py' or './playing_card.py'.
 The tests won't happen when this is imported from another module.

 Here are examples of the defined methods for this object.

    >>> from playing_card import Playing_Card                   # load it
    >>> king_of_diamonds = Playing_Card( rank=13, suit='d' )    # create one
    >>> random_card = Playing_Card()                            # create random one
    >>> print king_of_diamonds                                  # convert to string
    King of Diamonds
    >>> print king_of_diamonds.getRank()                        # get rank
    13
    >>> print king_of_diamonds.getSuit()                        # get suit
    d
    >>> print king_of_diamonds.BJValue()                        # get blackjack value
