 * A map cell trigger area is an box shaped area on the map with callbacks for various player events
 * Currently supported callbacks are:
 * Player enters area
 * Player leaves area
 * Periodic callback for all players within the area
 * Main uses:
 * enter waypoints, keep track of players in a certain region
