ClojureScript compiler should be easier to use

Setting up an initial environment is one of the more difficult things about getting started with ClojureScript. Developers coming from languages other than Clojure are often unfamiliar with Leiningen and project.clj can seem very foreign initially.

The goal of this project is to lower the barriers to entry for new ClojureScript developers and improve the usability of the ClojureScript compiler in general.
