[OpenWalnut-Dev] OSG Group Nodes

> Dear List

> I have added a new class "WGEGroupNode", which basically is a wrapper

> during the update cycle of the OSG. This is the way graph modifications 
> should be done (as intended by OSG).

Another thing to mention: as WGEGroupNode is inherited from osg::Group, you can 
and should use osg::ref_ptr< WGEGroupNode >.
