* most controllers turn out to be complete cork and thus can't be
reversed
* fixup a pair of simple controllers
TODO:
* fixup more controllers
* how can labels/page names be produced?
* grouping/categories of links?
At a high level, workings are pretty simple:
* iterate on all rules (every url pattern produces a werkzeug rule)
* check if the url can make sense as a link: GET, http, no auth or
public auth, coming from the CMS (no web client links) and all
converters can generate values for themselves (e.g. a url with an
`int` converter can't be generated as there is no finite set of
integers, let alone one small enough to make sense to show to users)
* check if the controller function bound to the URL can use the URLs
we can generate (no **kwargs as that means arbitrary get|post
parameter, no query param without a default value (a query param is
a parameter which does not come from a URL/rule converter))
* use rule converter(s) to generate a matrix of values, and build urls
from these
