@MrRobot2211 Woot on getting the autodocs building. Let me know when the other tasks are done and you'd like further review.

I've activated ReadTheDocs on this repository, so you should be able to see documentation builds now.

P.S. I'm not sure if ReadTheDocs can build branches from your repository, so I might have to copy this into a branch here to check that it works. Let me know when the ReadTheDocs configuration files are ready to go and then I can do that.

@hodgestar From what I've seen we should include QuTiP=devmajor inside doc.requirements.txt for this to build properly on read_the_docs side. But I might well be mistaken
