Polyatomic lattices could automatically create attributes (a, b, c, etc.) for all of their sublattices
So far, this feature is only provided by the likes of
kwant.lattice.honeycomb(), but I guess it would be useful generally, and probably it wouldn't hurt. It would be also easier to explain. Does anyone see any problems with this? If, for example, there is some lattice whose sublattices are habitually called X and Y, this could be confusing.
