More options for event-sample rescanning

[kilian]

The rescan command is now implemented and works, including structure functions. Currently, the event kinematics can be recovered, the sqme can be recalculated with new model parameters, and the weight can be rescaled according to the updated sqme.

Further options should be:

• update structure function parameters
• update parameters in scale/cuts/user weight (check current behavior!)
• update expressions for scale/cuts/user weight

Events that fail redefined cuts should be discarded.

As already hinted by WK, the analysis doesn't speak to weighted events (yet). However, at the moment this is not even caught by an error message, but the histograms are simply filled with some numbers.

I lost track completely, what is the staus of this ticket!?

For the third time: I did NOT get an answer!!!

Well, isn't that listed above?

The update expressions are most likely covered by the alternate environment list, which is implemented, but we rather need some review and use cases in order to finally confirm this. In any case, the missing support for weighted events should be added. I don't think that this is urgent, however.

Most desired options for rescanning are implemented and documented. There are some special bugs. (-> #657, #658). Closing this one.
