Jerry pointed out that respdiff.cfg needs more docs, especially when it comes to:

• which sections affect what tool
• what criterias and weights exists and what they do, how they match etc.

Match description can be mostly copied from https://gitlab.labs.nic.cz/knot/deckard/blob/master/doc/scenario_guide.rst#id1

Mapping config section to names is not straightforward as I thought because [diff] section configures [msgdiff] tool and diffrepro as well.
