//! The abstract class Conic describes the common <br>
//! behavior of conic curves in 2D space and, in <br>
//! particular, their general characteristics. The Geom2d <br>
//! package provides four specific classes of conics: <br>
//! Geom2d_Circle, Geom2d_Ellipse, <br>
//! Geom2d_Hyperbola and Geom2d_Parabola. <br>
//! A conic is positioned in the plane with a coordinate <br>
//! system (gp_Ax22d object), where the origin is the <br>
//! center of the conic (or the apex in case of a parabola). <br>
//! This coordinate system is the local coordinate <br>
//! system of the conic. It gives the conic an explicit <br>
//! orientation, determining the direction in which the <br>
//! parameter increases along the conic. The "X Axis" of <br>
//! the local coordinate system also defines the origin of <br>
//! the parameter of the conic. <br>
