Tesllation seems stable with new boundary handling procedure. Rooted out strange adjacency record-keeping due to some galaxies connecting to guard particles. Zobov still generates warning about guard particle encounters, but this is fine for observational datasets because we don't trust the tesselation at the edge galaxies anyway.
