//! Describes a parabola in 3D space. <br>
//! A parabola is defined by its focal length (that is, the <br>
//! distance between its focus and apex) and positioned in <br>
//! space with a coordinate system (a gp_Ax2 object) <br>
//! where: <br>
//! -   the origin of the coordinate system is on the apex of <br>
//!   the parabola, <br>
//! -   the "X Axis" of the coordinate system is the axis of <br>
//! symmetry; the parabola is on the positive side of this axis, and <br>
//! -   the origin, "X Direction" and "Y Direction" of the <br>
//!   coordinate system define the plane of the parabola. <br>
//! The equation of the parabola in this coordinate system, <br>
//! which is the "local coordinate system" of the parabola, is: <br>
//! Y**2 = (2*P) * X. <br>
//! where P, referred to as the parameter of the parabola, is <br>
//! the distance between the focus and the directrix (P is <br>
//! twice the focal length). <br>
//! The "main Direction" of the local coordinate system gives <br>
//! the normal vector to the plane of the parabola. <br>
//! See Also <br>
//! gce_MakeParab which provides functions for more <br>
//! complex parabola constructions <br>
//! Geom_Parabola which provides additional functions for <br>
//! constructing parabolas and works, in particular, with the <br>
//! parametric equations of parabolas <br>
