/* Main class for the Camp demo.  Assembles the user interface and the
   diagram components.

   Data objects are in the CampData class. CampData uses a different set
   of data objects for each reservation date.

   The background image is a map of the campground.  There is a
   display element for each campsite, read from the camp.elt file,
   which was created by positioning the campsites in Geo.

   Renderers are read from the camp.rdr file, and are defined so that
   the bounds of the elements remain constant across reservation
   dates. Because of this, the demo can set KeyModel's
   elementBoundsPolicy to indicate that the elements' bounds do not
   need to be recalculated when the data objects change, gaining a
   performance advantage.  */
