class now combines Cloner and DeepCopy into one class. Cloner and DeepCopy will be removed in next commit. Also have added osgcopy app to Demos which shows how the CopyOp have be subclassed to create users own specific handling of copying. Have fixed copy constructor problems in GeoSet which fix the deep copy problem experienced yesterday.
