  Uses modules: dtCore, dtABC, dtUtil
  
  Purpose
  -------
  To demonstrate the Delta3D lighting system. Our implementation is a thin
  object-oriented wrap of osg::Light and osg::LightSource, which is in turn a
  wrap of OpenGL vertex lighting. This example simply creates 3 lights in a 
  scene (not including the default scene light, which has been turned off 
  here) and demos their functionality. Light 1 is a spotlight rotating around
  the warehouse with continuously changing color. Light 2 is a yellow 
  positional light. The sphere is a Transformable child of Light 2 (i.e. when 
  Light 2 moves, the sphere moves). Light 3 is an infinite light (same as the 
  OpenGL directional light) and has the appearance of being located at an 
  infinite distance from the scene and therefore only it's direction and color
  can change (and change they do).
  
  Controls
