//! An algorithm to convert a sequence of adjacent
//! non-rational Bezier curves into a BSpline curve.
//! A CompBezierCurvesToBSplineCurve object provides a framework for:
//! -   defining the sequence of adjacent non-rational Bezier
//! curves to be converted into a BSpline curve,
//! -   implementing the computation algorithm, and
//! -   consulting the results.
//! Warning
//! Do not attempt to convert rational Bezier curves using this type of algorithm.
