@interhive Thank you for your contribution!

There have been a few changes ahead of this one. Please rebase with master and push again and then I will run tests and merge to master.

❄️ Happy Holidays ❄️

Good morning, @jcouball

I rebased with the master branch using GitHub's rebase feature. Let me know if you need anything else for this one!

Thanks and have a great holiday
