@davidrich27, thanks for the pull request.

I am probably too out of loop of looking at code to be super effective at managing this review, so I've also made @Haddox a repo admin so he can review and eventually merge.

I do have on requested change to note now though: update the version number here to match the CHANGELOG version increment.

[davidrich27]

@jbloom Yep, I made the version changes to metadata as well as the changelog.

I looked over the entire pull request and it looks good to me. We also made sure that we could reproduce the results in the tutorial.
