Rework NoteModel commands (not entirely successfully); remove FlexiNoteModel as it has always been almost entirely identical to NoteModel (unlike its layer counterpart)

- * Extension of the NoteModel for more flexible note interaction.

- * updated for FlexiNoteModel:
- *
- * Note type for use in a sparse model.  All we mean by a "note" is
- * something that has an onset time, a single value, a duration, and a
- * level.  Like other points, it can also have a label.  With this
