Notes

Typical calling sequence
PetscLayoutCreate(MPI_Comm,PetscLayout *);
PetscLayoutSetBlockSize(PetscLayout,1);
PetscLayoutSetSize(PetscLayout,n) or PetscLayoutSetLocalSize(PetscLayout,N); or both
PetscLayoutSetUp(PetscLayout);
PetscLayoutGetSize(PetscLayout,PetscInt *);

If the local size, global size are already set and range exists then this does nothing.
