Add preliminary MPI.
Add MPI headers. Initialize MPI with rank and nprocs and finalize MPI processes.
Add test for running a particular n.
Each process will run when n mod nprocs is equal to its rank.
Move output inside loop.
This way, it will print one array for each value of p.
Open file for output in print2DV.
File will be opened based on the p value.
Change output to file output.
Output to file stream output using fprintf in function in print2DV.
