Class for fillet calculation

Examples:

Calculate all possible fillets like:

>>> fillet = FilletCalculus2D(line_1, line_2, 1.0)
>>> for arc in fillet.GetFillets():
...     arc.Center, arc.StartAngle.Deg, arc.EndAngle.Deg
(Point2D(4, 0), 90.0, 180.0)
(Point2D(4, 0), 180.0, 450.0)
(Point2D(4, 2), 270.0, 540.0)
(Point2D(4, 2), 180.0, 270.0)
(Point2D(2, 0), 90.0, 360.0)
