W dS )a� Return the controller instance that "owns" the corresponding category.
This is more or less a workaround to the fact that spokes
need to know what's their controller, but the controllers
are indexed by hub name and spokes don't have a direct reference
to the hub they are displayed on.
Spokes know their category and hubs know what categories the and
categories should not be on two hubs. So we match the spoke category
to get the controller corresponding to the spoke.
:param str category_name: a spoke category name
:returns: a Controller instance "owning" the category or None if no matching instance is found

This function wraps the internal controller dictionary, so that it is not directly exposed.
The controller names currently correspond to hub class name, eq.:
SummaryHub, ProgressHub, etc.

Tell the controller that all expected modules have been registered
for initialization tracking (or have already been initialized)
and no more are expected to be added.
This is needed so that we don't prematurely trigger the init_done signal
when all known modules finish initialization while other modules have not
yet been added.
