Them mostly you missed a whole bunch of experimental code in classifier.py
get tested and thrown away again.  The code is more like it was now than it
was when you tuned out <wink>.

That or mboxtest.py (depending on your data setup) remain our two
cross-validation drivers, which I recommend.  timtest.py remains a grid
driver, and there's no reason to use it unless you want to set up brutal
tests (train on a little data and predict against a lot, N**2-N times).
