Clojurians Log v2

@albert.lai haven't tried it yet, just read some articles about it, but i also wish to replace schema with it. my problem is that boot or some boot plugins have issues with clojure 1.9.0-alpha11, so i don't want to complicate my life with it just yet

btw, i found a client side only alternative to https://www.websequencediagrams.com http://sequencediagram.org/

i highly recommend to use it for both documentation and algorithm design
