Yes, a version only with a graph (maybe +index-map) is needed and
I also didn't make any effort in using named parameters, yet. For this I
especially want to get feedback whether my approach for returning
the odd-cycle via one iterator is a good one. My headache with it
is that the user won't get the resulting iterator like in std::copy, because
the return-value is used for bipartiteness-predicate.

Thank you for this roadmap - I'll try to put some more effort into testing
and docs. As you said we're stuck on HTML, I assume I can gear on
the HTML source of the other docs and write mine in the same manner.
