This class implements the algorithms used to

//! centered on a point.
//! The arguments of all construction methods are :
//! - The qualified element for the tangency constrains
//! (QualifiedCirc, Line, Point).
//! - The center point Pcenter.
//! - A real Tolerance.
//! Tolerance is only used in the limits cases.
//! For example :
//! We want to create a circle tangent to an EnclosedCirc C1
//! with a tolerance Tolerance.
//! If we did not used Tolerance it is impossible to
//! find a solution in the the following case : Pcenter is
//! outside C1.
//! With Tolerance we will give a solution if the distance
//! between C1 and Pcenter is lower than or equal Tolerance.
