Root class for algorithms which convert a conic curve into
//! a BSpline curve (CircleToBSplineCurve, EllipseToBSplineCurve,
//! HyperbolaToBSplineCurve, ParabolaToBSplineCurve).
//! These algorithms all work on 2D curves from the gp
//! package and compute all the data needed to construct a
//! BSpline curve equivalent to the conic curve. This data consists of:
//! - the degree of the curve,
//! - the periodic characteristics of the curve,
//! - a poles table with associated weights,
//! - a knots table with associated multiplicities.
//! The abstract class ConicToBSplineCurve provides a
//! framework for storing and consulting this computed data.
//! The data may then be used to construct a
//! Geom2d_BSplineCurve curvSuper class of the following classes :
//! This abstract class implements the methods to get the geometric
//! representation of the B-spline curve equivalent to the conic.
//! The B-spline is computed at the creation time in the sub classes.
//! The B-spline curve is defined with its degree, its control points
//! (Poles), its weights, its knots and their multiplicity.
//! All the geometric entities used in this package are defined in 2D
//! space.
//! KeyWords :
//! Convert, Conic, BSplineCurve, 2D.
