Documentation for library

RethinkDB has awesome documentation with function level documentation, extensive code samples, and topic level docs. It could be good to use their examples and documentation, but port it to the Clojure driver.

It could be cool to use something like https://github.com/cljsinfo/cljs-api-docs#manual-docs to tangle the docstrings with manual docs.

Thoughts?

I will say that when using this lib, I very often consult: http://apa512.github.io/clj-rethinkdb/
