/*----------------------------------------------------------------
 *  This is an example from the Inventor Mentor
 *  chapter 14, example 2.
 *
 *  Use nodekits to create a scene with a desk into an 
 *  SoWrapperKit.  Then, add a material editor for the desk and 
 *  a light editor on the light.
 *  
 *  The scene is organized using an SoSceneKit, which contains
 *  lists for grouping lights (lightList), cameras (cameraList), 
 *  and objects (childList) in a scene.
 *  
 *  Once the scene is created, a material editor is attached to 
 *  the wrapperKit's 'material' part, and a directional light editor
 *  is attached to the light's 'directionalLight' part.
