[vtkusers] Match two meshes without collision

[Dženan Zukić]

If you want to match only the overlapping parts of 2 meshes, maybe you
should exclude the parts you know are not overlapping. If you don't know
that in advance, maybe some iterative approach might work:
1. Match meshes using all current points
2. Remove points which lie far away (relative wrt current points) from the
overlap
3. goto 1
