There was at least one previous version of midi2ly.  I'm not sure if
that version was fully in Python or in C++.  I seem to remember we tried
doing everything in Python and it being about 20 to 100 times slower.
For small midi files that does not matter much; so be sure to test with
large midi files, ouverture coriolanus comes to mind.
