This method parses the SVG document as rendered by OSMD and stores the graphical representations of the notes
in an array; notes are stored per measure (bar) in a sub-array so we end up with an array the size of the number
of bars, containing an array that contain the notes in that bar.
I use the following paths:
- openSheetMusicDisplay.GraphicSheet.MeasureList[0][0].staffEntries[0].graphicalVoiceEntries[0].notes[0];
- openSheetMusicDisplay.GraphicSheet.MeasureList[0][0].parentMusicSystem
