/******************************************************************************
TAPsOpenGLHalfEdgeModel.hpp

Class OpenGLHalfEdgeModel is for creating an OpenGL Polygonal Model using 
half-edge data structure.

See class HalfEdgeModel (in "../OpenGLModel/TAPsHalfEdgeModel.hpp") and
class OpenGLSupport ("../OpenGL/TAPsOpenGLSupport.hpp") for details.
