issue tomo reconstruction when forking
If I want to compare some reconstruction parameters one way would be to fork at one point having then two nabu or pyhst process. Then setting different parameters and running a reconstruction.
But in our the second reconstruction run will otherwrite the first one. We should (at least in nabu) have an option to avoid overwriting if configuration parameters are different. An other option would be to define an output manually by the user but this is less convenient for him.
