  This file contains a 3dsMax exporter derived from discreet's own SceneExport
  plug-in class; this exporter is basically a wrapper around the MaxToEgg
  Panda-converter class, and just sets up the interface and environment
  in which the MaxToEgg class can be "run" as if it were a standalone app.

/* This class defines the 3D Studio Max exporter itself.  It is basically a
   shell that is invoked by 3D Studio Max's export API.  It then sets up
   MaxToEgg instance and attempts to "fool it" into thinking that it is
   actually being invoked as a standalone program.  The thought behind this
   is that some day MaxToEgg may well be a standalone program, provided that
   a suitable interface to Max files can be connected from a standalone
   program instead of a plugin.
