funcool 2017-05-09

@niwinz thanks! I created a project and implemented specs for the other monads as well. https://github.com/caioaao/cats.spec

Still have to make It cljs compatible, but looks easy

Do you think it's worth to move it to funcool? I can change the copyright and transfer the ownership If needed. If not, I'll "release" it the way is 😬

It currently depends on my PR for the identity? pred, but I can change it to make it compatible with the released cats version
