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 allows to put the proxy definitions alongside with the
actually implementing service, which makes much more sense
than having all in one huge interfaceproxy.cpp file
