Detailed Description

This class implements the algorithms used to create 2d lines tangent to 2 other elements which can be circles, curves or points. More than one argument must be a curve.

Note: Some constructors may check the type of the qualified argument and raise BadQualifier Error in case of incorrect couple (qualifier, curv). For example: "EnclosedCirc".
