class  GCE2d_MakeParabola
 This class implements the following algorithms used to
create Parabola from Geom2d.
* Create an Parabola from two apex and the center.
Defines the parabola in the parameterization range :
]-infinite,+infinite[
The vertex of the parabola is the "Location" point of the
local coordinate system "XAxis" of the parabola.
The "XAxis" of the parabola is its axis of symmetry.
The "Xaxis" is oriented from the vertex of the parabola to the
Focus of the parabola.
The equation of the parabola in the local coordinate system is
Y**2 = (2*P) * X
P is the distance between the focus and the directrix of the
parabola called Parameter).
The focal length F = P/2 is the distance between the vertex
and the focus of the parabola.
