[Gmsh] boolean partitioning

[andrew]

This is what I came up with too. I create the geometry and import it to
gmsh as brep. The problem I have now is how to assign characteristic
lengths in individual groups (edges, surfaces). So far I haven't been able
to do that with a result that works correctly.

Kind regards
Andrew
