A playing card consists of a suit ("Hearts", "Spades", "Clubs", "Diamonds") and a value (2, 3, 4, 5, 6, 7, 8, 9, 10, "Jack", "Queen", "King", "Ace"). Implement a Card class. Implement that cards are equal when they have an equal rank, and that the other comparisons use the ranks in the order given above (2 lowest, Ace highest). Test the class.
