MetaEventTabController
======================

**class MetaEventTabController()**

Bases: :ref:`MetaController`

Shared base for the Controllers of the two event-oriented analysis tabs.

``RawDataController`` and ``EventAnalysisController`` both drive a tab that works
from a reader and a time-series channel rather than from a database of results:
the user picks a reader, a filter and a channel, and the tab finds or fits events
in the raw signal. The two carried two methods verbatim between them; this base
holds that shared half so there is one copy to fix.

What a subclass inherits:

- ``update_available_plugins``, which passes the app-wide plugin registry down to
  both the View and the Model when a plugin is instantiated anywhere.
- ``_resolve_callable_filter``, which fetches a filter plugin's callable for the
  paths that need one, or None where none was asked for or it could not be
  fetched.

What a subclass owes it:

- **Its own** ``logger = logging.getLogger(__name__)``, so records made by the
  methods it defines itself stay attributed to its own module.
- **``self.view`` and ``self.model``**, built in its ``_init()`` as
  ``MetaController`` requires.
