Clojurians Log v2

@whilo I actually have a bunch of RDF data from a WordNet, but I’m not sure if getting it into one of the Clojure Datalog dbs makes sense, or if I’m better off using either Apache Jena or Neo4j. I have no experience with either.

@simongray we've done a lot of benchmarking for Crux using RDF bench suites (LUBM and WatDiv, specifically), so there's quite a bit of code you could use or borrow in crux-bench and crux-rdf e.g. https://github.com/juxt/crux/blob/master/crux-rdf/src/crux/rdf.clj and https://github.com/juxt/crux/blob/master/crux-bench/src/crux/bench/watdiv.clj
