First draft integration of SURF and GTNetS. The code isn't even close to compile...

and in fact the API calls are not even in the repository (and some aren't fully implemented).
The point is to have something for Arnaud, Kayo, and Henri to look at. This should break
the build as the build system shouldn't really know about this code (but not quite sure about that
given that I never really looked into the cryptic build system)
