//! The  projLib package  first provides projection of <br>
//!          curves on a   plane along a  given Direction.  The <br>
//!          result will be a 3D curve. <br>//! The ProjLib package  provides projection of curves <br>
//!          on surfaces to compute the curve in the parametric <br>
//!          space. <br>
//! <br>
//!          It is assumed that the curve is on the surface. <br>
//! <br>
//!          It provides : <br>

//!          * Package methods to handle the easiest cases : <br>
//! <br>
//!            - Line, Circle, Ellipse, Parabola, Hyperbola on plane. <br>
//! <br>
//!            - Line, Circle on cylinder. <br>
//! <br>
//!            - Line, Circle on cone. <br>
//! <br>
//!          * Classes to handle the general cases : <br>
