Automatically Center Map

Add option to gmap center macro called 'auto'. Instead of putting in additional coordinates to center the map, use the waypoint itself as the center location. When listing a single waypoint this can be very to implement and extremely useful.

Later, if you want to get fancy then design to center on a group of waypoints.

I didn't find this option in the small amount of reading included in the gmap macro download. For what I want to do with gmap I can't think of any situation I'd never want to have the map automatically centered.

Any takers?
