[Therion] Distance between two survey station

Hi,
I once found a GPL2 library called "survex.py" from Thomas Holder.
Using that it is possible to find the shortest path (as you walk) 
between two points.
Survex itself just shows the shortest path as the crow flies.

I made a convinience wrapper "shortestPath.py" for the task, call 
example (linux):
$ ./shortestPath.py Hirlatzhoehle.Zubringer.1.1.0 
Hirlatzhoehle.Alter_Teil.2.1.55
('Shortest route length:', 2214.546790435116, 'm')
('Cumulated height going upwards:', 354, 'm')
('Cumulated depth going downwards:', -196, 'm')

I hope its useful,
greetings, Beni
