Clojurians Log v2

good morning people 🙂 , @cgrand what do you think about adding the lein-cljfmt plugin to unrepl? I started playing with what we talked about the global settings and I have a working version, but indentation changes create a lot of noise in the diff, so it might be a good idea to unify with cljfmt. Also maybe could add it to a CI tool as in unravel's #53, and as a first step to start adding a bit of tests to the project

@volrath PR welcome

@cgrand will do
