class WireEdgeSet from BOP inherits ShapeSet from BOP
---Purpose: The class containing data and methods
-- for a set of edges and wires
--
-- Bound is a wire,
-- Boundelement is an edge.
--
-- The ShapeSet stores :
-- - a list of wire (bounds),
-- - a list of edge (boundelements) to start reconstructions,
-- - a map of vertex giving the list of edge incident to a vertex.

Create
returns WireEdgeSet from BOP;
---Purpose:
--- Empty constructor;
---
Create (F: Face from TopoDS)
returns WireEdgeSet from BOP;
---Purpose:
--- Creates a WES to build edges connected by vertices
--- on face F. Edges of the WireEdgeSet must have a representation
--- on surface of face F.
---
Initialize(me:out;

---Purpose:
--- Initialize a WES to build edges connected by vertices
--- on face F. Edges of the WireEdgeSet must have a representation
--- on surface of face F.

---Purpose:
--- Indicates whether vertex V is a good connexity vertex between
--- edges E1 and E2.
--- i.e, returns True if V is shared by E1 and E2 and if V has different
--- orientations on E1 and E2.
--- If V is shared by E1 and E2, returns the orientation of V on E1 and E2

---Purpose:
--- Removes the edge aE from the WES
---
KeptTwice(me;

---Purpose:
--- Returns TRUE if the edge aE has been kept twice
--- in the WES
