Get PetscSFs that relate the pre-adaptation forest to the post-adaptation forest. Adaptation can be any combination of refinement, coarsening, repartition, and change of overlap, so there may be some cells of the pre-adaptation that are parents of post-adaptation cells, and vice versa. Therefore there are two PetscSFs: one that relates pre-adaptation coarse cells to post-adaptation fine cells, and one that relates pre-adaptation fine cells to post-adaptation coarse cells.
