Detailed Description

Provides methods to build wires.

A wire may be built :

     * From a single edge. <br>

From a wire and an edge.
- A new wire is created with the edges of the
  wire + the edge.
- If the edge is not connnected to the wire the
  flag NotDone is set and the method Wire will
  raise an error.
- The connection may be :
  
  . Through an existing vertex. The edge is shared.
  
  . Through a geometric coincidence of vertices.
  The edge is copied and the vertices from the
  edge are replaced by the vertices from the
  wire.
  
  . The new edge and the connection vertices are
  kept by the algorithm.
From 2, 3, 4 edges.
- A wire is created from the first edge, the
  following edges are added.
From many edges.
- The following syntax may be used :
  
  BRepLib_MakeWire MW;
  
  // for all the edges ...
  MW.Add(anEdge);
  
  TopoDS_Wire W = MW;
