PetscSFDuplicateOption

Aspects to preserve when duplicating a PetscSF

typedef enum {PETSCSF_DUPLICATE_CONFONLY,PETSCSF_DUPLICATE_RANKS,PETSCSF_DUPLICATE_GRAPH} PetscSFDuplicateOption;

 PETSCSF_DUPLICATE_CONFONLY - configuration only, user must call PetscSFSetGraph()

 PETSCSF_DUPLICATE_RANKS - communication ranks preserved, but different graph (allows simpler setup after calling PetscSFSetGraph())

 PETSCSF_DUPLICATE_GRAPH - entire graph duplicated
