@apcraig DO NOT MERGE THIS YET. I accidentally committed to this branch when testing the readthedocs stuff. I'll have to do another commit to fix it and will add a comment then.

I am just removing this one. I was messing with the .git files and directories, etc. when messing with readthedocs and I want to be triply sure none of those make it into the master repo.
