 * @author Shaz
 *
 * @help This plugin allows you to set an event to cover more than one tile
 * for collision purposes.  You can specify the entire event (all pages) to
 * have the large collision area, or just individual pages.
 *
 * USAGE:
 * Place the event in the top left corner of the area to be covered.
 * Enter <bigEvent:wxh|offset:ox,oy> in the event's note box (affects all event pages),
 * or as a comment on the event page (affects just that page), where w is
 * the number of tiles across and h is the number of tiles down that the
 * event will occupy and ox and oy is the collision box offset.
 * A <bigEvent:...> comment on an event page will override a <bigEvent...>
 * tag in the note box.
 *
 * Example:
 * <bigEvent:1x3|offset:-1,0> in the notebox of an event will expand the collision area
 * of that event to cover the current tile plus two tiles below (total width
 * is 1 and total height is 3) and offset the collision box one tile to the left.
 * <bigEvent:4x4> in a comment on an event page will expand the collision
 * area to a 4x4 square, just while that page is active.
 *
 * NOTE:
 * This plugin has no plugin commands.
 * This plugin is only to be used for events that will not move.
 *
