Russian verbs type 3, test module

I won't do it too fast and will try to document what I do. I've got other commitments and interests, of course. I'm sure, you'll be able to quickly fix if I do something wrong or inefficiently. Also, the most important is the result - the conjugation tables. If your solution gives the same result as mine and more efficiently, then your solution is better. Also, because I'll probably have to maintain and fix the module in the future, possibly train someone and document what it does and how, add new functions, it's important that I, whoever does it, knows the module well.

At the moment, I will just concentrate on the varieties of type 3 - I also think you wouldn't enjoy this part. The reference book, ru:wiki, and online references show a bit contradictory info on this type of verbs, so I'll have to decide on some verbs individually. Will think about two exceptions later. It'll be more fun when I start working with interchange of consonants.

Wishing you to resolve all your current problems and come back recharged. You don't have to answer if you're busy.
