OSSL Script Library/Teleport Map

This script will put a region map on the containing prim, and will instantly teleport the user to the map location that they clicked on.

The code contains a lot of comments, explaining what does what, and why it is there.

// Put a region map on a prim, and use that to teleport around.
// This teleport system is amazingly accurate.
// Do note that when a change is made to the region, the map on the 
// teleporter will only be updated when the rest of the world map is updated.
