//!This class implements the following algorithms used to <br>
//!          create Parab from gp. <br>
//!  Defines the parabola in the parameterization range  : <br>
//!  ]-infinite, +infinite[ <br>
//!  The vertex of the parabola is the "Location" point of the <br>
//!  local coordinate system (axis placement) of the parabola. <br>
//! <br>
//!  The "XDirection" and the "YDirection" of this system define <br>
//!  the plane of the parabola. <br>
//! <br>
//!  The "XAxis" of the parabola ("Location", "XDirection") is <br>
//!  the axis of symmetry of the parabola. The Xaxis is oriented <br>
//!  from the vertex of the parabola to the Focus of the parabola. <br>
//! <br>
//!  The "YAxis" of the parabola ("Location", "YDirection") is <br>
//!  parallel to the directrix of the parabola. <br>
//! <br>
//!  The equation of the parabola in the local coordinates system is <br>
//!  Y**2 = (2*P) * X <br>
//!  P is the distance between the focus and the directrix of the <br>

//!  The YAxis of the parabola is parallel to D and its location <br>
//!  point is the vertex of the parabola. The normal to the plane <br>
//!  of the parabola is the cross product between the XAxis and the <br>
//!  YAxis. <br>
