MILESTONE- Lilypond generation looking good! Lilypond generation now ignores line breaks. Fixed grammar to disallow pipe character. Fixed nasty bug by using clojure.zip instead of postwalk to convert data. Seems that postwalk was broken. DRYd up code for removing notation system prefixes (hindi- number- etc).  normalize-pitches was also rewritten using clojure.zip.  Removed some lilypond directives. Settled on the following: cadenzaOn ONLY. Added code to lilypond duration generation to handle case when rthythm was not in table. So now  17/33 will produce 17 tied notes and not blow up. Removed weird barNumber engraver lilypond directive. ALL TESTS LOOK GOOD. Copied good test results into own directory
