If predicate not given it just calls file-seq.
Why?
Ever went into a massive .svn directory? Now you can have tree-seq that prunes the entire path of enquiry and moves on.

Invoking (xml) produces default spec.
Tips:
- Uses clojure.data.xml/parse and clojure.data.xml/emit
- Feed to clojure.zip/xml-zip first
- clojure.data.zip.xml next: xml->, attr=, attr, :tag, tag=, text & text=
- clojure.zip/node within! xml-> will extract whole loc from zip
- xml-> returns sequence of matches.
