that is that RNA does not support multiple inheritance so the actual node group subtypes (ShaderNodeGroup, CompositorNodeGroup, TextureNodeGroup) can not be derived from both the
ShaderNode/CompositorNode/TextureNode base types as well as a common NodeGroup type ... It is possible however to define node group types entirely in python which avoids the limitations of the RNA system
and is much more flexible, example for this will follow later.
