/**
  @file demos/main.cpp

  This is a sample main.cpp to get you started with G3D.  It is
  designed to make writing an application easy.  Although the
  GApp/GApplet infrastructure is helpful for most projects,
  you are not restricted to using it-- choose the level of
  support that is best for your project (see the G3D Map in the
  documentation).
