Measure to retrieve the number of selected features #937

Closed sebffischer closed 8 months ago

requested by Bernd to support e.g. multicrit optimization of no of features and classification accuracy.

There is already a measure for this ("selected_features").

Can we maybe rename the measure, e.g. "n_selected_features" The current name suggests that it returns the selected features (I guess this is why Bernd and Martin were not aware of it).
