Comment (by jmantysalo):
About the name: If `A` and `B` are graphs, then `A.is_subgraph(B)` means
"A is a subgraph of B". If they are lattices, then `A.is_sublattice(B)`
means "B is a sublattice of A". So it is somewhat surprising difference.
But of course we can't add `is_sublattice()` to all iterables.
