class CORRISO from TopOpeBRepTool
--- Purpose : Fref is built on x-periodic surface (x=u,v).
-- S built on Fref's geometry, should be UVClosed.
--
-- Give us E, an edge of S. 2drep(E) is not UV connexed.
-- We translate 2drep(E) in xdir*xperiod if necessary.
--
-- call : TopOpeBRepTool_CORRISO Tool(Fref);
-- Tool.Init(S);
-- if (!Tool.UVClosed()) {
-- // initialize EdsToCheck,nfybounds,stopatfirst
--
-- Tool.EdgeWithFaultyUV(EdsToCheck,nfybounds,FyEds,stopatfirst);
-- if (Tool.SetUVClosed()) S = Tool.GetnewS();
-- }
