Simple neuroevolution example

nn.py contains the artificial neural network code
corridor.py contains the corridor navigating simulation
evolve.py runs evolution

to run:
python evolve.py evolve brain.dat [runs evolution for 200 generations, saves output brain in brain.dat]

to see the output:
python evolve.py load brain.dat [loads the brain stored in brain.dat and runs it in the corridor simualtion]
