@rkjones4 Shall we merge this PR?

@rodrigobdz Thank you for your interest in improving the repo! Unfortunately, I think this pull-request is too big of a structural change for me to approve, as I am no longer actively maintaining the repo, and would like to keep the core structure of it intact for archival purposes. I would suggest that you create a forked version of the repo with these improvements, and then I can add a link to this repo in the beginning of the README (indicating that it is a more up to date version). Best, Kenny

@rkjones4 I understand. Thus, the mention in the readme sounds like a good middle ground. My fork is available here: https://github.com/rodrigobdz/GANGogh
