Clojurians Log v2

@dave @jjttjj merged! i’ll look at pushing a new version tomorrow

Awesome, thanks!

@dave @jjttjj please give 3.10.0-SNAPSHOT a try

Not saying this actually should make it into javelin (it can always just be renamed in ns, but I really like the names new names micha gives to formula-of/formulet in the clj version I sent last night https://github.com/hoplon/javelin/pull/40

* The "formula-of" and "formulet" macros are now aliased to "fn=" and
  "let=", respectively, to save some typing and also it looks cool.

Im all for it!

looks like a good PR, needs a rebase now tho
