/******************************************************************************
PolygonalModel.hpp

A (Generic) Polygonal Model contains:
    char *      m_pcObjectName;     // object name
    int         m_iNoVertices;  // # of vertices
    int         m_iNoFaces;     // # of faces
    int         m_iNoTexCoords; // # of texture coordinates
    Vertex<T> * m_prVertex;         // Vertex pointers
    Face<T> *   m_prFace;           // Face pointers

Each property should be set explicitly 
including the NORMAL of each m_prVertex and m_prFace
except the following:
  - m_pcObjectName (is for identification, not important)
  - m_iNoTexCoords (must be set if use with texture)
