Hi Arvind, 

I have never done a pull request before so I am not quite sure if I did everything correctly. The neural network files look better, but I still have a few updates to go before I am fully satisfied with them. If you have any comments on how they look now, feel free to send that my way! 

I am hoping to extend the functionality of the neural network in the upcoming months to support different types of networks, as well as different activation functions.
