Aggressive coarsening and 2- stage MM-ext Interpolations on GPUs (#195) 
This PR contains the following changes:
* Aggressive coarsening, i.e, 2nd SoC on GPUs
* 2-stage MM-ext Interpolations (MM-ext, MM-ext+e) on GPUs
* Enhanced abilities of extracting strong FF/FC/CF/CC submatrix with given SoC matrix
* Bug fix in device PMIS

Fix AMGDD (#190) 
This PR fixes some memory leaks of BoomerAMGDD. Additional topics covered are:

* Perform code refactoring to meet the style used in hypre.
* Add GetIterations and FinalResidual interfaces for BoomerAMGDD.
* Add new regression tests.
* Make FAC Relaxation dependent on the execution policy.

AMG-DD implementation (#145) 
This includes the implementation of the AMG-DD algorithm, a variant of BoomerAMG designed to limit communication. 

AMG-DD may be used as a standalone solver or a preconditioner for Krylov methods (note that AMG-DD is a non-symmetric preconditioner). For an example of how to set up and use AMG-DD, see the IJ driver (src/test/ij.c).

A list with the parameters of AMG-DD is given below:

Padding (recommended default 1): HYPRE_BoomerAMGDDSetPadding(...)
Number of ghost layers (recommended default 1): HYPRE_BoomerAMGDDSetNumGhostLayers(...)
Number of inner FAC cycles per AMG-DD iteration (default 2): HYPRE_BoomerAMGDDSetFACNumCycles(...)
FAC cycle type: HYPRE_BoomerAMGDDSetFACCycleType(...)
1 = V-cycle (default)
2 = W-cycle
3 = F-cycle
Number of relaxations on each level during FAC cycle: HYPRE_BoomerAMGDDSetFACNumRelax(...)
Type of local relaxation during FAC cycle: HYPRE_BoomerAMGDDSetFACRelaxType(...)
0 = Jacobi
1 = Gauss-Seidel
2 = ordered Gauss-Seidel
3 = C/F L1-scaled Jacobi (default)

For more details of the algorithm, see Mitchell W.B., R. Strzodka, and R.D. Falgout (2020), Parallel Performance of Algebraic Multigrid Domain Decomposition (AMG-DD).
