 * Plugin Command
 * =============================================================================
 * This plugin command is copying an event.
 * MapID : if the value is zero or - 1, the mapId will set up an id of currently map.
 * Event Copy X Y MapID EventID
 *
 * This plugin command deletes a previously created event on currently map.
 * Event Delete EventID
 *
 * This plugin command creates a new event on currently map.
 * Event Create X Y CharacterName CharacterIndex
 *
 * =============================================================================
 * Script Calls
 * =============================================================================
 * RS.Event.instanceCopy(x, y, mapID, eventID, customData);
 * customData : if its value sets to null, it will use existing event data.
 *
 * RS.Event.instanceDestroy($gameMap.events().last);
 * =============================================================================
 * Change Log
 * =============================================================================
 * 2015.10.17 (v1.0.0) - First Release Date
