class WireExplorer from BRepTools
---Purpose: The WireExplorer is a tool to explore the edges of
-- a wire in a connection order.
--
-- i.e. each edge is connected to the previous one by
-- its origin.
-- If a wire is not closed returns only a segment of edges which
-- length depends on started in exploration edge. If wire has
-- singularities (for example, loops) WireExplorer can return not all
-- edges in a wire. it depends on type of singularity.
