Group publications by research groups

[michaelfromyeg]

Though the authors used currently are technically research groups, the results aren't very accurate. Provide an option such that:

• for author given, fetch the publications
• grab data that is in the form research_group: [faculty_member, ..., faculty_member]
• re-organize publications by those groups;
• if a publication doesn't have an author that belongs to a group, discard it
• if a publication has authors belonging to multiple groups, majority rules
