pkgdown site

[pcarbo]

@eweine It looks like you've put a lot of work into the vignettes (which is great!).

Would it be worth building these into webpages using pkgdown? If you give me write access, I can do that for you. (Or perhaps I have write access already?)

I agree this would be nice eventually. There's just quite a bit going on there right now so I would prefer to wait until we finalize results for the paper.
