sq1 able to loop through damp and strn hypre parameters
Sq0 can now also do damping and strn param changes
header for 2D lagrange square
Sq0 now using rayheader
rayheader now determines if the damping/strenght needs to be set, by
seeing if it is set. If it's < 0, it is not set, therefore do not call
it.
Added new Hypre parameters:
CLJPGSStrn0668, CLJPJStrn0668, CLJPPilutStrn0668,
RSGSStrn0668, RSJStrn0668, RSPilutStrn0668
Added more preconditioners to the tests for the momemtum block.
12 is default NS, 17 is the modified NS.
Updated sq2 to handle more preconditioners.
Also I am using the "correct" boundary conditions now.
