Ipad41001

-- ABCplayerCodea version 0.1.4
-- Plays ABC musical notation format tunes on the Codea/Codify iPad platform. 
-- By Fred Bogg, November 2011.  Improvements welcome. Thanks to ipda41001 for coding assistance.
-- This program defines musical notes and chords, parses an ABC format tune, creates a table
-- of notes to be played with their durations, and then plays it.  With the parsing done 
-- first, playback is possible without slowing down draw frames (psuedo-background).

-- 0.1.4
-- DEBUG to self.DEBUG, stopped passing it around
-- soundTablePointer to self.soundTablePointer
