Pytorch Implementation of BatchNorm

Batch Normalization is a really cool trick to speed up training of very deep and complex neural network. Although Pytorch has its own implementation of this in the backend, I wanted to implement it manually just to make sure that I understand this correctly. Below is my implementation on top of Pytorch's dcgan example (BN class starts at line 103)

Although this implementation is very crude, it seems to work well when tested with this example. To run this, type in
$ python --cuda --dataset cifar10 --dataroot .
