+class InterCurveCurve from Geom2dAPI 
+
+	---Purpose: This class implements methods for computing
+    	-- -       the intersections between  two 2D curves,
+    	-- -       the self-intersections of a  2D curve.
+    	-- Using the InterCurveCurve algorithm allows to get the following results:
+    	-- -      intersection points in the  case of cross intersections,
+    	-- -      intersection segments in the case of tangential intersections,
+    	-- -       nothing in the case of no intersections.
