 *
 * Holds a vector of Card objects.  This class contains no
 * dynamically allocated data members, so the default copy
 * constructor and assignment operators are used.
 *
 * This is the base class of DrawPile, LaydownPile, and PlayerHand.
 * It provides methods to add cards, count, check for emptiness,
 * and print the card pile.
