One problem to use Cython is write all the "header" files to link
cython with the GRASS library, the good news is that I've tried to
generate these files automatically using: cwrap and it seems to
work fine through clang frontend. but I don't have enough time to test
I would like to translate some lower part of the pygrass library to
use cython and see if and how much the speed gain is.
