*-*                    =======================
*-*
*-*    A TNode object is used to build the geometry hierarchy (see TGeometry).
*-*    A node may contain other nodes.
*-*
*-*    A geometry node has attributes:
*-*      - name and title
*-*      - pointer to the referenced shape (see TShape).
*-*      - x,y,z offset with respect to the mother node.
*-*      - pointer to the rotation matrix (see TRotMatrix).
*-*
*-*    A node can be drawn.
