Clojure intro and 4clojure.com workshop

Unfortunately Bruce Hauman's travel plans have changed and he won't be able to give a talk, so we'll go with the backup plan instead:

We will meet to work on 4Clojure (http://www.4clojure.com/) problems instead. The 4clojure.com site has a bunch of clojure code snippets with a blank space for you to fill in. They range from simple, first time using clojure problems that take some head scratching to solve.

Anyone interested in Clojure can make a 4clojure account and try a few problems. Bring a laptop to the event and together we can help with installation or IDE issues, work on some problems, and even code-golf a few to see who can find the shortest solution.
