class IntersectionTool from ShapeFix

	---Purpose: Tool for fixing selfintersecting wire
	--          and intersecting wires

uses

    Face from TopoDS,
    Edge from TopoDS,
    Vertex from TopoDS,
    ReShape from ShapeBuild,
    WireData from ShapeExtend,
    DataMapOfShapeBox2d from ShapeFix,
    Curve from Geom2d,
    Box2d from Bnd
