class FClass2d from IntTools

    	---Purpose: Class provides an algorithm to classify a 2d Point
    	---         in 2d space of face using boundaries of the face.

	---Purpose:
	--- Returns state of the 2d point Puv.
	--- If RecadreOnPeriodic is true (defalut value),
	--- for the periodic surface 2d point, adjusted to period, is
	--- classified.

    	--- Test a point with +- an offset (Tol) and returns
    	--- On if some points are OUT an some are IN
    	--  (Caution: Internal use . see the code for more details)
