 //! This class implements the algorithms used to
 //! create a 2d circle tangent to a 2d entity,
 //! centered on a 2d entity and with a given radius.
 //! More than one argument must be a curve.
 //! The arguments of all construction methods are :
 //! - The qualified element for the tangency constrains
 //! (QualifiedCirc, QualifiedLin, QualifiedCurvPoints).
 //! - The Center element (circle, line, curve).
 //! - A real Tolerance.
 //! Tolerance is only used in the limits cases.
 //! For example :
 //! We want to create a circle tangent to an OutsideCurv Cu1
 //! centered on a line OnLine with a radius Radius and with
 //! a tolerance Tolerance.
 //! If we did not use Tolerance it is impossible to
 //! find a solution in the following case : OnLine is
 //! outside Cu1. There is no intersection point between Cu1
 //! and OnLine. The distance between the line and the
 //! circle is greater than Radius.
 //! With Tolerance we will give a solution if the
 //! distance between Cu1 and OnLine is lower than or
 //! equal Tolerance.
