//! This class provides the analytic intersection between <br>
//!          a conic defined as an element of gp (Lin,Circ,Elips, <br>
//!          Parab,Hypr) and a quadric as defined in the class <br>
//!          Quadric from IntAna. <br>
//!          The intersection between a conic and a plane is treated <br>
//!          as a special case. <br>
//! <br>
//!          The result of the intersection are points (Pnt from <br>
//!          gp), associated with the parameter on the conic. <br>
//! <br>
//!          A call to an Intersection  L:Lin from gp and <br>
