Handle base case of directory?

[arichiardi]

Hello James, this tiny library here really saved me from the Java purgatory: I was already kind of picturing myself banging my head on the wall while trying to make sense out of Java resources and methods to fetch them when I stumbled across it.

Big thanks.

One thing I have noticed, maybe by design, is that directory? does not handle the case where the input url is nil, which can happen when chaining directly, for example in this sample (cut for brevity):

;; Java resources are the best, how to know if the resource path is a dir?
;; http://stackoverflow.com/questions/20105554/is-there-a-way-to-tell-if-a-classpath-resource-is-a-file-or-a-directory
(->> (str path (when-not (= \/ (last path)) "/")) 
     (.findResource classloader)
     (res/directory? r))

Is it something you would like to add by any chance?

I think that's a good idea. A :default case that just returns false would be a sensible addition, and I'd welcome a PR to that effect.
