Helped the scene manager to depart from the scene. The viewer and editor

applications really need to deal directly with the scene repository. The
display part of the MISO code doesn't need a scene manager, per se,
because it is simply told to visualize a particular scene and scene
management happens entirely externally. This is in preparation for making
the MISO code work and place nicely with the Whirled code.
