class EdgeConnector from BRepAlgo inherits TShared from MMgt

    ---Purpose: Used by DSAccess to reconstruct an EdgeSet of connected edges. The result produced by
    --           MakeBlock is a list of non-standard TopoDS_wire,
    --          which  can present connexions of edge  of  order > 2 
    --           in certain  vertex. The method  IsWire
    --            indicates standard/non-standard character of  all wire produced.
