Save experiement
Experiment with result and raw data should be saved (into an .h5 file for example).
This is why an addOperation should be added to the Experiment class. This would add to the stack of operation a name and the set of parameters used for this operation:
- roi selection
- noise removal ... This would be called before the 'send' of the orange processing ? Or exported in the processing (would be better I guess if we want to remove the orange part one day. So this way can be an update operation).
