INITIAL COMMIT: pysle - python interface to ISLEX dictionary

Code tested over a decent corpus.  Features:

- look up phone and syllable info for the
  canonical pronunciation of a word

- map an actual pronunciation to a dictionary
  pronunciation (can be used to automatically find
  speech errors)

- automatically syllabify a textgrid containing words
  and phones (e.g. force-aligned text)
