/**
 * Describes a parabola in 3D space. A parabola is defined     by its focal
 * length (i.e. the distance between its focus     and its apex) and is positioned
 * in space with a     coordinate system where: - the origin is     the apex
 * of the parabola, - the "X Axis"     defines the axis of symmetry; the parabola
 * is on the     positive side of this axis, - the origin, "X     Direction"
 * and "Y Direction" define the     plane of the parabola. This coordinate
 * system is the     local coordinate system of the parabola. The "main  
 * Direction" of this coordinate system is a vector     normal to the plane
 * of the parabola. The axis, of which     the origin and unit vector are
 * respectively the origin     and "main Direction" of the local coordinate
 * system, is termed the "Axis" or "main     Axis" of the parabola. The "main
 * Direction" of the local coordinate system gives an     explicit orientation
 * to the parabola, determining the     direction in which the parameter increases
 * along the     parabola. The Geom_Parabola parabola is parameterized as
 * follows: P(U) = O + U*U/(4.*F)*XDir + U*YDir where: - P     is the point
 * of parameter U, - O, XDir and YDir are     respectively the origin, "X
 * <br>     Direction" and "Y Direction" of its local     coordinate system,
 * - F is the focal length of the     parabola. The parameter of the parabola
 * is therefore its     Y coordinate in the local coordinate system, with
 * the     "X <br> Axis" of the local coordinate     system defining the origin
 * of the parameter. The     parameter range is ] -infinite, +infinite [.
