I didn't change in any of the conda things, I just changed the name of the directory and file. Let me know if I should try to fix the conda part (aka get Nathan to help me with it).

@bannanc - please set with Nathan to make sure everything gets moved over to smirnoff rather than smirff (including package name, stuff in setup.py, conda-recipes/meta.yaml, etc. (It's not actually in THAT many places so you should be able to do most of it yourself, probably by searching the repo for the word smirff!) and then do a new release and push a new build to the conda channel.

I'm OK with it being merged once you guys are ready, and this does not necessarily have to be done all in one PR.

I renamed all instances of smirff to smirnoff, I'm going to merge for now and I'll check with Nathan about how to change the conda channel with the name change

Thanks, @bannanc . Will also need to do a new point release for that via the "releases" tab on GitHub.
