deferred class Intersection from IntRes2d


    ---Purpose: Defines  the root   class  of  all  the  Intersections
    --          between  two 2D-Curves, and  provides all  the methods
    --          about the results of the Intersections Algorithms.


uses IntersectionPoint             from IntRes2d,
     IntersectionSegment           from IntRes2d,
     SequenceOfIntersectionPoint   from IntRes2d,
     SequenceOfIntersectionSegment from IntRes2d
