//! This class provides an algorithm for constructing a Bezier surface filled from
//! contiguous Bezier curves which form its boundaries.
//! The algorithm accepts two, three or four Bezier curves
//! as the boundaries of the target surface.
//! A range of filling styles - more or less rounded, more or less flat - is available.
//! A BezierCurves object provides a framework for:
//! -   defining the boundaries, and the filling style of the surface
//! -   implementing the construction algorithm
//! -   consulting the result.
//! Warning
//! Some problems may show up with rational curves.
