Score one for unit testing

I'll tell you, having extensive unit tests written that the system already passed before this major overhaul makes me ... let's put it this way. It makes it possible to do refactoring like this. I would definitely have lost hope without my unit tests, and this project would be another dead one. Instead, I'm taking the old unit tests, dropping them into the directory, and letting the unit tests quickly and easily find the places in the code that need attention.

I've almost got everything working again. Incroyable!
