[Wikidata] Freebase Sets (based on Google Sets)

I recently asked <https://twitter.com/thadguidry/status/1247635376094707712> an old Freebase colleague @narphorium to graciously spend some time to write up what was once a very cool Freebase app that many of us used in Freebase to see overlap of Freebase Properties (like WD statements) between 1-5 Freebase Topics (like WD Items) that then ran a query to find other Topics that matched that overlapping set. I thought that sharing this knowledge would allow others to get inspired and learn and possibly build a similar shape tool for Wikidata; if not already existing. It is just a small README.md in the repo below. Freebase Sets https://github.com/narphorium/freebase-sets Thad https://www.linkedin.com/in/thadguidry/
