 * Description:
 * 	Contains functions to produce random pair of playing card images.  Images
 * 	are located in the ./images/cards directory.  This is intended to simulate
 * 	a hand of Texas Holdem.
 *
 * NOTE: This is currently not being used because the functionality of showing a
 * different random set of cards on each refresh is not the preferred method.
 * see ../php/random_card.php for an option to show a different random card each 
 * day.
