package IntWalk

	---Purpose: This package defines the "walking" (marching?)algorithmes
	--          for the intersection between two surfaces.
	--          One of the surfaces is a parametric one.
	--          If the other is an implicit one, the "IWalking" class will
	--          be used.
	--          If both surfaces are parametric, the "PWalking" class will
	--          be used.

        ---Level: Internal

        -- All the methods of the classes of this package are Internal.
