 * NAME:        Geometry Library (C++)
 *
 * COMMENTS:
 *      This class is used as a base class for all patch types supported.
 *      The vertex list management is handled by this class, however, all
 *      other function should be handled by the subclass.
 *      The insertRow and insertCol are meant to be virtual since it
 *      may be possible for the patch type to insert a row or column
 *      without distorting the shape of the patch (as in NURBs or MESH)
 *
