Detailed Description

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.
