/**
* BatchNode holds geometries that are a batched version of all the geometries that are in its sub scenegraph.
* There is one geometry per different material in the sub tree.
* The geometries are directly attached to the node in the scene graph.
* Usage is like any other node except you have to call the {@link #batch()} method once all the geometries have been attached to the sub scene graph and their material set
* (see todo more automagic for further enhancements)
* All the geometries that have been batched are set to {@link CullHint#Always} to not render them.
* All the geometries that have been batched are set to not be rendered - {@link CullHint} is left intact.
* The sub geometries can be transformed as usual, their transforms are used to update the mesh of the geometryBatch.
* Sub geoms can be removed but it may be slower than the normal spatial removing
* Sub geoms can be added after the batch() method has been called but won't be batched and will just be rendered as normal geometries.
