Dividing labels #11

I noticed that in donkeys.lua you are dividing the labels by 20. Could you explain why you did that?

This was to comply with the original caffe code. This is actually equivalent to getting a learning rate 20 times as high, so I don't think it's very useful, but pretrained models from caffe output flow/20 so the training code is designed to make the network learn to output this exact amont, for compatibility purpose, with applications that were already using flownet from caffe
