Split EXACT-ISH.f90 into aaron_main.f90 and jipu_main.f90
Renamed Makefile to makefile because the capital letter was bugging me.  Also updated makefile to build openmp and openacc modules and both aaron_main.exe and jipu_main.exe executables.  Everything builds correctly.
Adding openacc and openmp modules for jipu and I to write our separate kernels in.  They are both empty right now, except for a USE statement.
Removed messed up edit in validate() routine, and changed the error checks to be a relative error instead of absolute.
Having the %spwee2D_prodquad_P0 procedure pointer get associated in fspSolver instead of sweeper.  Since fspSolver uses openmp and openacc modules, this will allow for the procedure pointer to be assigned with routiens in those modules while keeping them separate from the main sweeper module.
