class DSFiller from TopOpeBRep

    ---Purpose: Provides class  methods  to  fill  a datastructure
    --          with  results  of intersections.
    --          
    --          1.  Use  an    Intersector  to   find    pairs  of
    --          intersecting GeomShapes
    --          
    --          2. For each  pair fill the DataStructure using the
    --          appropriate Filler.
    --          
    --          3. Complete the  DataStructure to record shapes to
    --          rebuild (shells, wires )
