Closes https://leanprover.zulipchat.com/#narrow/stream/458659-Equational/topic/Central.20groupoids.

This PR contains a number of results on central groupoids and natural central groupoids.

This is a draft PR.

  • Ensure that @zaklogician's work is not destroyed here - probably the simplest way is to move that file to NonnaturalCentralGroupoids.lean
  • Give an example of an implication that reduction can disprove
  • Add a module doc which more clearly highlights the key results here
