this function creates a lilypond file using the prevously save data

this function takes a lilypond string and turns it into two arrays of notes and durations used with ToneJS

var lilycode = "\\relative c' {c4 d e f g1}";
var results = translateLilyToToneJS(lilycode);
// results[0] = ["C4","D4","E4","F4","G4"]
// results[1] = ["4n","4n","4n","4n","1n"]

this function returns the keySig, tempo and timeSig from the lilyPondAdapter object
