Fix website so documentation links work again

[qdot]

Getting a lot of 404s going to the docs.nonpolynomial.com, which I took down a long time ago. I should just add the research papers to the git repo and link there, as well as point the project site to my portfolio page, versus trying to have it as its own site.

This is a good idea as the research paper links to 'kyle.machul.is' are broken too.
A 'papers' folder in the 'docs' directory should do the trick.
