7e2a19cf4c 1. Add some more block interpolations and one more modified unknown 
interpolation.

2. Fixed hybrid method to work with aggressive coarsenings.

3. Updated stats for block matirx to use a different norm.

4. Added -NodalDiag options to treat diagonal entries differently in
nodal coarsening.

76dd7a0eac Added several new solver types to AMS which use scalar solvers in the 
domains of Pi_x, Pi_y and Pi_z. Those require less memory compared to
the full Pi.

673c8709ee made various improvements for long range interpolation operators: 
- extended interpolation is now like modified , i.e no absolute values anymore
- added an extended interpolation which only extends when there are no common coarse neighbors
- changed standard interpolation to only extend at strong F neighbors (which corresponds
  common definition), not all neighbors anymore, for better efficiency

9ee452e699 Added a helper function, HYPRE_AMSConstructDiscreteGradient(), which can 
be used to construct the discrete gradient matrix based on some edge and
vertex information. This will be used to simplify the use of AMS in some
user codes (ALE3D).

04ceb1465f changed the hybrid again to work with Kull. Setup is now empty, everything takes place 
in the solve, without continually creating and destroying the solvers if the hybrid is
to be reused, also the preconditioner is stored and can be reused.

12bd5d9baa potentially improved performance of coarsening and interpolation by using 
different Commpkg for strength matrix S. Added a new parameter S_commpkg_switch
which sets the smallest strength threshold, for which this capability is used.
This required the addition of a new parameter (int array that maps S-indices
to A-indices) to the interpolation routine.
Note that while this change does not affect Falgout, CLJP, PMIS and HMIS
convergence behaviour and complexities, it affects ruge, ruge2b and ruge3c.
This can be avoided by setting S_commpkg_switch to 1.

a7ae5273bd added GMRES and BiCGSTAB to the ParCSRHybrid Solver. PCG is the default, 
but GMRES (or BiCGSTAB) can be used by setting solver_type to 2 for GMRES
or 3 fro BICGSTAB with HYPRE_ParCSRHYbridSetSolverType.

96cb9359da removed the function and parameter int *smooth_option and replaced 
it by int smooth_type and int smooth_num_levels,
where smooth_type defines the type of complicated smoother (i.e. no
point smoother, e.g. Schwarz, Euclid, etc.) and smooth_num_levels the
number of levels for which the smoother is used starting with the finest level.

7aa95e4b53 added (inner and outer) relaxation parameters to Gauss-Seidel routines, 
also added a backward solve procedure.
This required an additional parameter for hypre_BoomerAMGRelax.
Complete list of  choices for smoothers are now:
relax_type = 0 -> Jacobi or CF-Jacobi
relax_type = 1 -> Gauss-Seidel <--- very slow, sequential
relax_type = 2 -> Gauss_Seidel: interior points in parallel, boundary sequential
relax_type = 3 -> hybrid: SOR-J mix off-processor, SOR on-processor with outer relaxation parameters (forward solve)
relax_type = 4 -> hybrid: SOR-J mix off-processor, SOR on-processor  with outer relaxation parameters (backward solve)
relax_type = 5 -> hybrid: GS-J mix off-processor, chaotic GS on-node
relax_type = 6 -> hybrid: SSOR-J mix off-processor, SSOR on-processor  with outer relaxation parameters
relax_type = 9 -> Direct Solve
