/*:
 * @plugindesc Allows events or players to do smart Pathfinding
 * @author Shaz
 *
 * @help
 *
 * This is merely a fork of Shaz's SMARTPATH plugin. I've added some extra
 * functionality to be able to auto-cancel the pathfinding as well as to 
 * have the event interpreter WAIT while the pathing takes place.
 *
 * Plugin Command:
 *  SmartPath eventId1 eventId2      # Makes event 1 find path to event 2
 *  SmartPath eventId x y            # Makes event find a path to location x, y
 *  SmartPath eventId cancel         # Cancel Pathfinding for event
 *
 *  event = number for specific event
 *  event = 0 for "this" event
 *  event = -1 for player
 *  event = $gameVariables.value(x) to get the event id from variable x
 *
 *  x, y = coordinates or $gameVariables.value(#) to use a variable coordinate
 *
 * Update by DragoonKain:
 *   Use Game_Interpreter.findEvent to allow specifying events by name.
 *   Added Wait, Auto_Cancel and Auto_Cancel_Near.
