All of the existing "simple" tests for the »Diff Framework« are way to much low-level;
they might indeed be elementary, but not introductory and simple to grasp.
We need a very simplistic example to show off the idea of mutation by diff,
and this simple example can then be used to build further usage test cases.
My actual goal for #1206 to have such a very basic usage demonstration and then
to attach a listener to this setup, and verify it is actually triggered.
PS: the name "GenNodeBasic_test" is somewhat pathetic, this test covers a lot
of ground and is anything but "basic". GenNode in fact became a widely used
fundamental data structure within Lumiera, and -- admittedly -- the existing
implementation might be somewhat simplistic, while the whole concept as such
is demanding, and we should accept that as the state of affairs
