Ichthyostega dddcbe9994 DOC: supply basics of UI-Bus and generic UI-element protocol
the initial draft of this concept is in place now, and
the first round of unit tests pass. I've got some understanding
of the purpose of the interactions and involved elements
and I'm confident this design is evolving in a sane way.

Note: extensive documentation is in the TiddlyWiki,
here I've just pasted and reworded some paragraphs from there
and integrated them into the Doxygen docs

/** @file abstract-tangible-test.cpp
** Verify the common base shared by all interface elements of relevance.
** This test is not so much a test, than a test of the test support for testing
** [primary elements][gui::model::Tangible] of the Lumiera GTK UI. Any such element
** is connected to the [UI-Bus][gui::UiBus] and responds to some generic actions and
** interaction patterns. This is the foundation of any presentation state recording
** and restoration, and it serves to invoke any persistent action on the
** [Session] through a single channel and access point.
**
** What is covered here is actually a **test mock**. Which in turn enables us
** to cover interface interactions and behaviour in a generic fashion, without
** actually having to operate the interface.

/** @test verify the UI widget unit test support framework.
* The generic backbone of the Lumiera UI offers a mock UI element,
* with the ability to stand-in for actual elements present in the real GUI.
* This allows us to rig a emulated test user interface to cover interactions
* involving some communication from or to interface elements. After setting up
* a [MockElm] with a suitable name / ID, we're able to operate this element
* programmatically and to send messages and responses from the core "up"
* to this mocked interface. And since this mock element embodies an
* [event log][EventLog], the unit test code can verify the occurrence
* of expected events, invocations and responses.
*
* \par connectivity
* Any mock element will automatically connect against the [Test-Nexus][test/test-nexus.hpp],
* so to be suitably rigged for unit testing. This means, there is no _live connection_
* to the session, but any command- or other messages will be captured and can be
* retrieved or verified from the test code. Since lifecycle and robustness in
* "post mortem" situations tend to be tricky for UI code, we provide a dedicated
* ["zombification"][gui::test::TestNexus::zombificate()] feature: a [MockElm] can be turned
* into an _almost dead_ state, while still hanging around. It will be detached from the
* "living" Test-Nexus and re-wired to some special, hidden "Zombie Nexus", causing any
* further messaging activity to be logged and ignored.
