* Refactor sparse models.  Previously the 1D and time-value models duplicated
  a lot of code; now there is a base class (SparseModel) templated on the
  stored point type, and the subclasses define point types with the necessary
  characteristics.

* Add NoteModel, a new SparseModel subclass.

* Reorganise local feature description display.  Instead of asking the layer
  to draw its own, just query it for a textual description and draw that in
  Pane.  Greatly simplifies this part of the layer code.

* Add local feature descriptions to colour 3D plot and waveform layers.

* Add pitch in MIDI-pitch-and-cents to spectrogram layer.

* Give AudioGenerator its own mutex to shorten lock times in CallbackPlaySource.

* Minor adjustments to layers menu &c
