class QuadQuadGeo from IntAna
---Purpose: Geometric intersections between two natural quadrics
-- (Sphere , Cylinder , Cone , Pln from gp).
-- The possible intersections are :
-- - 1 point
-- - 1 or 2 line(s)
-- - 1 Point and 1 Line
-- - 1 circle
-- - 1 ellipse
-- - 1 parabola
-- - 1 or 2 hyperbola(s).
-- - Empty : there is no intersection between the two quadrics.
-- - Same : the quadrics are identical
-- - NoGeometricSolution : there may be an intersection, but it
-- is necessary to use an analytic algorithm to determine
-- it. See class IntQuadQuad from IntAna.
