 *
 *
 * This plugin adds four plugins commands to be used in your events:
 *
 * 1. TarotShuffle
 * This command just shuffles the tarot deck. No arguments.
 *
 * 2. TarotClear
 * Clear the cards on the screen
 *
 * 3. TarotInterpretation
 * Display a message with a random fortune telling.
 * I suggest you to use a message plugin with wordwrap support (eg Yanfly Message Core),
 * because the generated messages are big.
 *
 * 4. TarotSpreadCard <X> <Y> <R>
 * 
 * This is the main command to be used. This command will display a card on the position X, Y.
 * Please note that X and Y use the card height as units, not pixels.
 *
 * To display the Celtic Cross spread, use the following sequence:
 *
 *    TarotShuffle
 *    TarotSpreadCard 2 2 0
 *    TarotSpreadCard 2 2 90
 *    TarotSpreadCard 2 3 0
 *    TarotSpreadCard 1 2 0
 *    TarotSpreadCard 2 1 0
 *    TarotSpreadCard 3 2 0
 *    TarotSpreadCard 4 4 0
 *    TarotSpreadCard 4 3 0
 *    TarotSpreadCard 4 2 0
 *    TarotSpreadCard 4 1 0
 *    TarotInterpretation
 *    TarotClear
