Add missing :delimiter parameter to example.
parse returns a lazy seq of vectors, delimiter support, parsing strings.
This restructures the ideas of my last two commits: - Parse now takes a reader and the options :mapped, :delimiter and :quoter. - Added two helper-functions parse-file and parse-string which take a filename and a string resp. - Updated the documentation for those functions.
Added the possibility to let parse return a lazy-seq of vectors instead of maps and added supprt for using custom delimiters.
