New description:
Do some polishing to `is_chain_of_poset()`, `maximal_antichains()` and so
on at `posets.py`.
Bugs:
{{{
P = Posets.BooleanLattice(3).relabel(lambda x: chr(ord('a')+x))
P.maximal_chains(partial=['b','c'])
}}}
outputs `['b', 'c', 'd', 'h']` which is not a chain at all.

Comment:
Found a bug -> type changed to defect.
Which one is correct: "Return the chains of the poset.", "Return all the
chains of the poset.", "Return all chains of the poset." or "Return chains
of the poset."?
