annotate layer/NoteLayer.h @ 77:fd348f36c0d3

* Implement harmonic cursor in spectrogram * Implement layer export. This doesn't quite do the right thing for the SV XML layer export yet -- it doesn't include layer display information, so when imported, it only creates an invisible model. Could also do with fixing CSV file import so as to work correctly for note and text layers.
