How does this fit into DMDACreate*D()?  Are you changing the create API
as well?

PetscErrorCode DMDACreate3d(MPI_Comm comm,DMDABoundaryType bx,
DMDABoundaryType by, DMDABoundaryType bz, DMDAStencilType
stencil_type,PetscInt M,PetscInt N,PetscInt P,PetscInt m,PetscInt
n,PetscInt p,PetscInt dof,PetscInt s,const PetscInt lx[],const PetscInt
ly[],const PetscInt lz[],DM *da)
