Solving 4clojure problems in an editor

On Twitter xeqixeqi asked for a leiningen template to be able to solve to the problems from 4clojure in an editor rather than the browser. He then solved this problem himself by building a lein template for 4clojure.

I did most of the problems in emacs by copy-pasting the test cases from each problem page. To turn the text on 4clojure into a runnable test I used this utility: gist: 4clojure in editor.
