//! This class implements the algorithms used to
//! create 2d circles tangent to 3 points/lines/circles.
//! The arguments of all construction methods are :
//! - The three qualified elements for the
//! tangency constraints (QualifiedCirc, QualifiedLine,
//! Points).
//! - A real Tolerance.
//! Tolerance is only used in the limit cases.
//! For example :
//! We want to create a circle tangent to an UnqualifiedCirc
//! C1 and an UnqualifiedCirc C2 and an UnqualifiedCirc C3
//! with a tolerance Tolerance.
//! If we do not use Tolerance it is impossible to find
//! a solution in the following case : C2 is inside C1
//! and there is no intersection point between the two
//! circles, and C3 is completly outside C1.
//! With Tolerance we will find a solution if the
//! lowest distance between C1 and C2 is lower than or
//! equal Tolerance.
