Hi Glynn, Hamish, all,

the split is done in r40303, and there are no more errors during make.
It's far than perfect, so testing and comments are welcome :) 
ATM, the "Plot variogram" in GUI is not functional as it is matter of
global variables. I'm looking at this now. 

I don't understand what is the problem with #!/usr/bin/env python. How
can the scripts use GRASS_PYTHON instead? How is the link between this
and import wx?
Thanks in advance for any hint and sorry if I'm missing something
important.

best,
Anne
