Either

** lattices
- In add_site_family, the first argument cannot be a general site family, it must be a lattice from lattice.py. We should rename site_family -> lattice in this context. In fact, that argument could be even a Polyatomic lattice (that is not a site family at all).
- The automatically selected other_vectors could be longer but more orthogonal.
