sPuReMD: further OpenMP work on force computations and interaction lists. Minor data structure scope changes. Fix numereous non-critical memory leaks. Add tear-down code. Other general refactoring.

sPuReMD: begin merging code from LAMMPS USER-REAXC-OMP/USER-OMP. Fix ACKS2 charge matrix coefficients.

PG-PuReMD: complete memory changes. Remove max register per CUDA function option in build. Other misc. changes.

sPuReMD: fix linear solver to work with no preconditioner. Fix issue when precondition recomputation frequency is zero. Other misc. changes.

PG-PuReMD: only perform device-side reductions on energy at requested update energy frequency. Fix trajectory file output. Add num. retries of main simulation loop to log file. Other refactoring.

PG-PuReMD: fix nvcc build issue where incorrect C++ compiler was utilized. Fix race condition with three body list computation. Remove debug code. Other misc. refactoring.

PG-PuReMD: begin enhancements. Enable sim. step retries. Enable far neighbors list max per atom. Other general code clean-ups.

PG-PuReMD: fix build system linker argument ordering (LDFLAGS -> LDADD). Fix inline functions. Disable optimized CUDA code generation by default (added Makefile flags to enable along with preprocessor defs to enable relevant code paths).

PG-PuReMD: fix include guards, resolve implicit function declarations, fix inline issues with GCC v5 (C99 std). Other general code clean-up.

PG-PuReMD: fix issue with hydrogen bond cutoff with systems without hydrogen atoms. Remove debugging info for MPI-only version of PG-PuReMD.

PG-PuReMD: include forgotten headers for distribution. Fix CUDA installation check. Additional updates for build system.
