//! This class implements the following algorithms used
//! to create a CylindricalSurface from Geom.
//! * Create a CylindricalSurface parallel to another and
//! passing through a point.
//! * Create a CylindricalSurface parallel to another at a
//! distance
//! <Dist>.
//! * Create a CylindricalSurface passing through 3 points.
//! * Create a CylindricalSurface by its axis and radius.
//! * Create a cylindricalSurface by its circular base.
//! The local coordinate system of the CylindricalSurface is defined
//! with an axis placement (see class ElementarySurface).
//!
//! The "ZAxis" is the symmetry axis of the CylindricalSurface,
//! it gives the direction of increasing parametric value V.
//!
//! The parametrization range is :
//! U [0, 2*PI],  V ]- infinite, + infinite[
//!
//! The "XAxis" and the "YAxis" define the placement plane of the
//! surface (Z = 0, and parametric value V = 0)  perpendicular to
//! the symmetry axis. The "XAxis" defines the origin of the
//! parameter U = 0.  The trigonometric sense gives the positive
//! orientation for the parameter U.

  //! such that the normal Vector (N = D1U ^ D1V) is oriented towards
  //! the "outside region" of the surface.

  //! Radius = 0.0
