NS: Default BCs are free-slip on all faces
If no boundary conditions are set at command line, there will be free-slip boundary conditions on velocity components on all faces
The use still has the possibility of imposing wall boundary conditions (which sets all three components of velocity to homogeneous Dirichelet condition)
If the user specify both conditions, slip and wall, on the same face sets, the program will error

NS: Use non_zero_time=false for problem type avection
Since exact solution and error calculation is not currently provided for the 3D advection case, this flag should be set to false for now
With non_zero_time=true the program was always reporting Max Error: 0. for problem type advection

fluids: fix -viz_refine by composing interpolation matrices
This also changes -petscspace_degree to -degree (using
PetscFECreateLagrange, which is now available).
Example parallel run with -viz_ref
