示例1: Unflip
/// <summary>
/// Transform two triangles to two different triangles by flipping an edge
/// clockwise within a quadrilateral. Reverses the flip() operation so that
/// the data structures representing the triangles are back where they were
/// before the flip().
/// </summary>
/// <param name="flipedge"></param>
/// <remarks>
/// See above Flip() remarks for more information.
///
/// Upon completion of this routine, the 'flipedge' handle holds the edge
/// cd of triangle cdb, and is directed up, from vertex c to vertex d.
/// (Hence, the two triangles have rotated clockwise.)
