cubicweb #707104 Facets for selected attributes [open]

It would be great if facets were generated according to what attributes were selected in the RQL.

For example, the following RQL

Any X,D,T WHERE X is BlogEntry, X creation_date D, X modification_date T

Could generate two slide selectors for dates, one for creation_date and the other for modification_date. If these are different from the ones on the side, they could be displayed on top of the results a bit like the filter forms.
