Poisson 2D with linear elements. I've been testing GMRES with a mesh up
to 196x196, and up to 300x300 with BiCGStab. Just need to implement a
preconditioner and all the demos should run sufficiently fast without
PETSc. I think that this is important for people who want to take a
quick first look at DOLFIN and don't want to be bothered with difficult
dependencies (ie, something you have to build yourself). The simplicity
of uBlas also makes it ideal experimenting with new solvers and
preconditioners.
