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