//! This class implements construction algorithms for an ellipse in

//! A MakeEllipse object provides a framework for:
//! - defining the construction of the ellipse,
//! - implementing the construction algorithm, and
//! - consulting the results. In particular, the Value
//! function returns the constructed ellipse.

//! Warnings :
//! The MakeEllipse class does not prevent the

//! If an error occurs (that is, when IsDone returns
//! false), the Status function returns:
//! - gce_InvertRadius if MajorRadius is less than MinorRadius;
//! - gce_NegativeRadius if MinorRadius is less than 0.0;
//! - gce_NullAxis if the points S1 and Center are coincident; or
