  SFunction () ;

  Default constructor.
  This constructor resets the arc length and registers this as the current arc length function. Only one such function may be active at any time.

  Return arc length at center SC().

  static double arcIn () ;

  Return arc length at entrance SI().

  static double arcOut () ;

  Return arc length at exit SO().

  void reset () ;

  Reset the arc length to zero.

  void update (double) ;

  Advance position by element length.

  ~SFunction () ;

  Destructor.
  Unregister this as the current arc length function.
