PetscOmpCtrlCreate

create a PETSc OpenMP controller, which manages PETSc's interaction with third party libraries using OpenMP

#include "petscsys.h"  
PetscErrorCode PetscOmpCtrlCreate(MPI_Comm petsc_comm,PetscInt nthreads,PetscOmpCtrl *pctrl)

	petsc_comm	- a communicator some PETSc object (for example, a matrix) lives in
	nthreads	- number of threads per MPI rank to spawn in a library using OpenMP. If nthreads = -1, let PETSc decide a suitable value

pctrl -a PETSc OpenMP controller

TODO: Possibly use the variable PetscNumOMPThreads to determine the number for threads to use
