up to now inVRs has no own namespace.
So the default namespace will fill up more and more and it become more and more difficult to track, which features are part of inVRs and which aren't.
The idea is to introduce namespaces in inVRs.
the question is whether only one namespace (inVRs) or a hierarchy of namespaces (e.g. inVRs/SystemCore,...) should be created.
The other thing is how to accomplish backward compatibility
