    	---Purpose: Splits a 2d curve with a criterion.

    Create returns mutable SplitCurve2d from ShapeUpgrade;
    	---Purpose: Empty constructor.

    Init (me: mutable; C: Curve from  Geom2d);
       	---Purpose: Initializes with pcurve with its first and last parameters.
	
    Init (me: mutable; C          : Curve from  Geom2d;

       	---Purpose: Initializes with pcurve with its parameters.
	
    Build (me: mutable; Segment: Boolean) is redefined;
       ---Purpose: If Segment is True, the result is composed with
       --  segments of the curve bounded by the SplitValues.  If
       --  Segment is False, the result is composed with trimmed
       --  Curves all based on the same complete curve.
