[Geoqus] earth stress field

[Tobias Lau]

Hi Gabriele,

sadly my knowledge about python is quite small jet, but I'm trying to improve
it. So I don't have any script for the horizontal stress right now (for this I
used CAE) but when I finished writing one I will gladly accept your offer and
send it to you.

Cheers,
Tobias
