//!Root class for algorithms which convert an elementary <br>
//! surface (cylinder, cone, sphere or torus) into a BSpline <br>
//! surface (CylinderToBSplineSurface, ConeToBSplineSurface, <br>
//! SphereToBSplineSurface, TorusToBSplineSurface). <br>
//! These algorithms all work on elementary surfaces from <br>
//! the gp package and compute all the data needed to <br>
//! construct a BSpline surface equivalent to the cylinder, <br>
//! cone, sphere or torus. This data consists of the following: <br>
//! - degrees in the u and v parametric directions, <br>
//! - periodic characteristics in the u and v parametric directions, <br>
//! - a poles table with associated weights, <br>
//! - a knots table (for the u and v parametric directions) <br>
//! with associated multiplicities. <br>
//! The abstract class <br>
//! ElementarySurfaceToBSplineSurface provides a <br>
//! framework for storing and consulting this computed data. <br>
//! This data may then be used to construct a <br>
//! Geom_BSplineSurface surface, for example. <br>
//! All those classes define algorithmes to convert an <br>
//! ElementarySurface into a B-spline surface. <br>
//! This abstract class implements the methods to get <br>
//! the geometric representation of the B-spline surface. <br>
//! The B-spline representation is computed at the creation <br>
//! time in the sub classes. <br>
//! The B-spline surface is defined with its degree in the <br>
//! parametric U and V directions, its control points (Poles), <br>
//! its weights, its knots and their multiplicity. <br>
//! KeyWords : <br>
//! Convert, ElementarySurface, BSplineSurface. <br>
