# This is an example from the Inventor Mentor
# chapter 14, example 2.
#
# Use nodekits to create a scene with a desk into an 
# coin.SoWrapperKit.  Then, add a material editor for the desk and 
# a light editor on the light.
# 
# The scene is organized using an coin.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.
