Title: Doc tidy up.

Fixes some warnings/errors in the sphinx build (but not all, as they are **really** hard to track down).

Adds the ability to do a ```python make.py linkcheck``` to find dead links (of which there are still some, but I will make a separate issue for that).

Adds the new capability of running ```python make.py doctest``` to test that our documentation examples make sense/still function. These are not unit tests, merely a chance to make certain that our documentation isn't giving erroneous examples (currently there are only a limited number of doctests, and I do not propose we make a concerted effort to grow the number).
