doc build and dependencies

[hjoliver]

#3 moved all docs here from the cylc-flow repository, simplistically taking the relevant bits of setup.py and cylc-check-software with it.

We need to decide how best to build the docs here, and how best to depend (where necessary) on other project/repo versions, particularly cylc-flow. (e.g. should we use setup.py here at all?)

Related to this one, we have an issue in setup.py that prevents the project from building in a new virtual environment. We have sphinx in install_requires. And we also do import sphinx in setup.py. The problem is that the import in setup.py is evaluated first, resulting in an ImportError.

Using setup_requires could solve it, if that was evaluated by pip. We could alternatively hack setup.py and install sphinx if not present. But I think that depends first on the decision pending in this issue.
