Comment (by jmantysalo):
Level sets are defined on every poset, or actually on every acyclic
digraph.
But still I don't know what is wanted. For example `Poset({0:[1,2], 1:[3],
3:[4], 4:[5], 6:[5]})` is ranked, is it rank-symmetric? For now only
connected graded posets seems to have clear definition of what is rank-
symmetry.
