okay, but that's IT!

I promised myself I'd stop working on this. My goal is to put together some rudimentary documentation, post the source and be done with it for a while. But lying in bed tonight unable to sleep seemed unproductive, so I implemented another selection strategy in addition to the generational/constant population approach, which is to killing off all a-lifes below an energy threshold and breeding those above. This now happens pretty frequently, and the results seem to be much faster evolution.
