Clojurians Log v2

hi. implemented a simple idea to allow running a function over the atom state when :inspect-data true is used. check out the PR and issue here and if anyone wants to try it, you can check out the branch from my repo, lein install and use it. I'm using it at work and already loving it. would appreciate feedback and pointers on the code (if i forgot anything)
