Thank you for challenging me on my choice of wording. I shouldn't have suggested that the repo was interesting without properly exploring the contents myself. I only discovered that git repo after reading the article this morning and since I am at work I have not been able to explore the code myself. I posted the link just to share it with anyone else that might be interested.
