NSE: Solver seems to work fine in 2d. Added support for using AMG (algebraic
multigrid) using Hypre in main-file. To use Hypre it has to be installed on
the system, then run the program with flags accordingly:

> ./dolfin-navierstokes-benchmark -pc_type hypre -pc_hypre_type boomeramg

The convergence of the GMRES solver is dramatically accelerated using Hypre,
both for the momentum and the continuity equations.
