11. Simplifying Datomic Syntax by Writing a DSL

The context here is that creating schema and writing inserts for Datomic are unnecessarily verbose, especially for people who think in Clojure.

Instead of using the Datomic shell, we’ll use an in-memory version of Datomic that we access from Clojure.
