Thanks! Backwards compatibility for generators and test function
fixtures is now working nicely in nose2.

My next topic will be how to handle output/logging capture and attach
those buffers to test reports without monkeying with _exc_info_to_str,
which I've learned from nose is harmful to small animals and other
people who don't want buffer contents splattering into their output in
inappropriate places. I'll work on it a bit (next week maybe) and come
back with some more feature requests if needed.
