at the point when we're connecting a new node to the UI-Bus,
the new node's BusTerm is not yet initialised, since we need
the uplink connection we're about to create for setting up
this BusTerm.
Consequently, the new nodes's ID is not yet initialised,
so we need to pass this endpoint-ID explicitly to the
registration function.
since, by definition, the Nexus is "the" up-link,
all we need is clever overriding of the relevant
handling functions, so the nexus will care for the routing,
while the CoreService cares for command and presentation
state handling
...providing the standard implementation of UI-Bus connectivity.
It seems reasonable to place all of the UI-Bus implementation into
a single translation unit
what you see here now is just the tip of the icebearg...
If we follow this route, the Lumiera UI will become way more
elaborate and responsive than average desktop applications
over time, a specific Lumiera code writing style has emerged.
The GUI, as it stood, used somewhat different conventions,
which now have been aligned to the common standard.
Basically we use GNU style, with some adjustments for OO-programming,
we prefer CamelCase, and write TypeNames uppercase, variableNames lowercase
This is the first step towards a generic backbone to connect
any GUI elements to the session within Proc-Layer.
It is based on a spefic understanding of Model-View-Controller,
which turns the Model-Controller interactions into messages.
