PetscSFView() never called viewer for the specific type (bug), hence many output files were incorrect.

Added PetscSFView() support for basic MPI implementation and binary viewer saves communication

PetscSFView() never called viewer for the specific type (bug), hence many output files were incorrect.

Added PetscSFView() support for basic MPI implementation and binary viewer saves communication data to binary file.
This new viewer shows exactly how much data is sent from each rank to the other ranks
allowing fiting various performanace models to the data.

This uses MatView() to save the PetscSF data, but since Mat is above PetscSF in the software stack
the code will not work with multiple PETSc libraries. How should this be managed if one wishes to preserve the
traditionl PETSc algorithm stack?

Update sfbasic.c save the transpose of the matrix since that indicates the sends for each rank which is easier to understand
