package IntAna

    ---Purpose: This package provides the intersections between :
    --          
    --          - Natural Quadrics when the result is a conic (QuadQuadGeo)
    --          
    --          - A natural Quadric and a Quadric defined by its Coefficients
    --            (IntQuadQuad)
    --            
    --          - 3 Pln   (Int3Pln)
    --          
    --          - a Line and a Torus   (IntLinTorus)
    --          
    --          - a Conic from gp and  a Quadric  defined by its Coefficients
    --            (IntConicQuad)
    --
