It's inconvenient to have two datasets with the same case insensitive name: SciDocs & SCIDOCS. E.g. MacOS is by default case insensitive.

Let's rename SciDocs? I'd propose SciDocsS2S or SciDocsRR instead, but maybe someone has a better idea.

Also do I understand correctly that SciDocs is the same SciDocs as in useb? I.e. it includes all the tasks of Cite, Co-Cite, Co-Read, Co-View, see their paper for details (+ recomm).

cc @loicmagne as I think you added it?
