I know this is still a work-in-progress, but just wanted to call out that it would be nice to get some usage information for http://hvac.readthedocs.io/ as outlined in https://github.com/hvac/hvac/blob/master/CONTRIBUTING.md#examples whenever you get to that point. 👍

Oh and do you think you'll have time to wrap up the changes in this PR over the next week or so? (If so, I'll tag it for the 0.6.5 milestone.)

@tiny-dancer: Fair warning, I'm planning on wrapping up the changes you have started here and will push those updates to your branch over the next couple days. 😀
