Doc listing of everything

[rogerbinns]

It is a bit difficult to get a listing of every method of every class / module etc with one line description

There is autosummary but it generates one item eg if given Connection doesn't include a listing of every method/attribute. We could probably generate the autosummary items.

There is also autoclasstoc that gives the same idea https://autoclasstoc.readthedocs.io/en/latest/index.html
