"""First load the survex stations for entrances and fixed points (about 600) into the database.
Run cavern to produce a complete .3d file, then run 3dtopos to produce a table of
all survey point positions. Then lookup each position by name to see if we have it in the database
and if we do, then save the x/y/z coordinates. This gives us coordinates of the entrances.
If we don't have it in the database, print an error message and discard it.
