Add cave view
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The old class hierarchy of displays and render modules is becoming antiquated. It is difficult to add new view types and there are issues with reimplementing client/server for every type of view.
We want to redesign the view classes. This work needs to be coordinated with similar work on the Titan project that is developing a similar hierarchy for VTK.
