From Tan Dunning and Jan Peciva, Jan's email : "I created a new submission, based on Tan's two changes, including further naming functionality that includes:

- geode and geometry naming
- shaders and osg::Program name

as these nodes did not receive names before. Some code cleaning included as well."
