class FaceRestrictor from BRepAlgo
---Purpose: Builds all the faces limited with a set of non
-- jointing and planars wires. if
-- <ControlOrientation> is false The Wires must have
-- correct orientations. Sinon orientation des wires
-- de telle sorte que les faces ne soient pas infinies
-- et qu'elles soient disjointes.

-- The edges of <W> can be modified if they have not pcurves
