//! This class defines a complete surface of revolution.
//! The surface is obtained by rotating a curve a complete revolution
//! about an axis. The curve and the axis must be in the same plane.
//! If the curve and the axis are not in the same plane it is always
//! possible to be in the previous case after a cylindrical projection
//! of the curve in a referenced plane.
//! For a complete surface of revolution the parametric range is
//! 0 <= U <= 2*PI.       --
//! The parametric range for V is defined with the revolved curve.
//! The origin of the U parametrization is given by the position
//! of the revolved curve (reference). The direction of the revolution
//! axis defines the positive sense of rotation (trigonometric sense)
//! corresponding to the increasing of the parametric value U.
//! The derivatives are always defined for the u direction.
//! For the v direction the definition of the derivatives depends on
//! the degree of continuity of the referenced curve.
