Test join operations on fiber bundles.
I proposed scenario:
- I drawn ROI and extracted all fibers that are passing through that ROI
- Then I performed NOT operation on ROI and extracted fibers as well
- Then I joined fibers and I expected to have whole brain
- To check that I substracted fibers from point 3) from original fibers. I expected to get nothing .... but MITK crashed. I checked that twice .
