troggle/parsers/survex.py
Martin Green a128401d49 Added parsing of all.svx, along side parsing individual caves.
Added the making and parsing of all.pos to determine the location of stations.
Mare work is required so the caves are parsed and stored only once.
Survex parsing appears to include bugs, that print out errors.
