Comment:
The current branch fixes the bug. The rationale is to allow posets to not
have a specified linear extension. This is achieved by changing the input
behavior of `FinitePoset`. If `elements` is specified, this is used for
the underlying linear extension. If `elements` is None, then the default
linear extension is now computed in the `__init__`, so that posets where
linear extensions are not specified now compare equal.
