This brings me a lot of joy. Despite it being poorly-organized function soup, I hope being able to view a framework-free source was valuable to you. I learned most of what I knew from viewing source way back in the mid-nineties and that's a lot of the reason I chose not to obfuscate it in production so others could do the same.

and not a chemist? :)

I was awestruck by the tool web "app" and not the stuff that it covered. I am just as impressed today as I was years ago by looking at the different interactions.
