[petsc-users] PetscSF Fortran interface

[Nicholas Arnold-Medabalimi]

Hi Junchao

Thanks again for your help in November. I've been using the your merge
request branch quite heavily. Would it be possible to add a
petscsfcreatesectionsf interface as well?
I'm trying to write it myself using your commits as a guide but I have been
struggling with handling the section parameter properly.

Sincerely
Nicholas
