[petsc-dev] PetscHMapI passing

[Mark Adams]

To add a method to PETSc there are several places that you need to add
headers and registration stuff.
I find a method that looks like my method and clone that by searching (git
grep) for that (DMPlexGet something) method and cloning that code
everywhere that you find that method.
