class Coincidence from HLRAlgo
---Purpose: The Coincidence class is used in an Inteference to
-- store informations on the "hiding" edge.
--
-- 2D Data : The tangent and the curvature of the
-- projection of the edge at the intersection point.
-- This is necesserary when the intersection is at
-- the extremity of the edge.
--
-- 3D Data : The state of the edge near the
-- intersection with the face (before and after).
-- This is necessary when the intersection is "ON"
-- the face.
