Explain suicide continued

stats.core1295.csv: I seem to have corrected the fitness statistic by this stage, since the value correlates with what the expected number of grandchildren ought to be. (Less than 4 if the population has declined, greater than 4 if it has increased, 4 if it is stable.) Actually, I think I remember this was when I had to redo the fitness so I attributed the fitness to the right epoch. (That is, record the fitness of the agent in the epoch in which it was born, rather than in the epoch in which I can finally calculate the fitness because the agent and its children have all died.) Still, that change shouldn't make much difference to the per-epoch average. I probably corrected something else as well.
