Hello DOLFIN!

I added an interface to the CHOLMOD sparse cholesky solver in the dolfin
sandbox. CHOLMOD is written by the guy who wrote UMFPACK and it is part
of the same distribution (both source and deb), so it really does not
add a new dependency if included in the lib. CHOLMOD was benchmarked in
this paper in ACM TOMS:
http://portal.acm.org/citation.cfm?doid=1236463.1236465 and came out on
top (for symmetric definite systems).

Nice. I just added it.

We should rename

   scons/simula-scons/simula_scons/pkgconfiggenerators/umfpack.py

as

   scons/simula-scons/simula_scons/pkgconfiggenerators/suitesparse.py

and add a test for CHOLMOD. When that's done, the solver can be moved
into dolfin/la.

I think it is perhaps better to add a new pkgconfig generator cholmod.py
and keep the old umfpack.py as it is. Is that okay with you?


Fine with me. Can you add it?
