API for java-utils - clojure-contrib v1.3 (in development)

Overview

A set of utilties for dealing with Java stuff like files and properties.

Design goals:

(1) Ease-of-use. These APIs should be convenient. Performance is secondary.

(2) Duck typing. I hate having to think about the difference between
    a string that names a file, and a File. Ditto for a ton of other 
    wrapper classes in the Java world (URL, InternetAddress). With these
    APIs you should be able to think about domain equivalence, not type
    equivalence.

(3) No bossiness. I am not marking any of these functions as private
    the docstrings will tell you the intended usage but do what works for you. 					

Feedback welcome!

If something in this module violates the principle of least surprise, please 
let me (Stu) and the Clojure community know via the mailing list.
