39//! This class provides the analytic intersection between a
40//! cylinder or a cone from gp and another quadric, as defined
41//! in the class Quadric from IntAna.
42//! This algorithm is used when the geometric intersection
43//! (class QuadQuadGeo from IntAna) returns no geometric
44//! solution.
45//! The result of the intersection may be
46//! - Curves as defined in the class Curve from IntAna
47//! - Points (Pnt from gp)
