/******************************************************************************
TAPsOpenGLHalfEdgeTrigonalModel.hpp

Class OpenGLHalfEdgeTrigonalModel is for creating an OpenGL Trigonal Model 
using half-edge data structure.

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