1-layer backpropagation works
Merge branch 'master' into backprop
populations
backprop seems to work for multiple layers
Merge remote-tracking branch 'origin/backprop' into backprop
live learning maybe working. immediate feedback doesn't do much
5x5, single sim with stats
removed old saves and stats (there were bugs)
huge refactor again. evolution_bot is easier to read. added Collective population
fixed hindsight; added group_lesson; incubate.py
minimap simulation and "good/bad/neutral" debug messages.

problem is that still too many actions are neutral
refactored learning bots into subfolder; separated bots from testing code
Merge branch 'backprop'
