It looks like our bot automatically created this pull request. The main three changes in this version are the following:

1) Documentation now exists for all user-facing functions. 2) R CMD check should be passing. (It looks like the vignette is causing it to fail on the GitHub server. I created an issue about that.) 3) Binomial regression is now implemented.

There are a few other minor optimizations and bug fixes as well. It looks like I accidentally created a few lint issues while doing this. I will try to push a quick patch to fix those.

I pushed a minor fix this morning that removed the vignette and fixed a couple linting issues that I overlooked. It looks like all of our tests are passing now. Hooray!
