annotate layer/TimeInstantLayer.h @ 30:ea6fe8cfcdd5

* Add the Note layer for pianoroll-type display of note-type data * Complete the MIDI file importer (well, nearly -- it would be nice to be able to import the non-note data as other sorts of models, and that's not done yet). * Minor refactoring in RealTime etc
