  Consider adding a EventTreeNode pointer to every Event.  This would
greatly speed moving from one arbitrary event to it's predicessor
or successor.  Speed up would be reflected in reading large files
where noteoff search for their pairing noteon.  But I'll hold off
on this - it would increase each Event by a pointer.  This has been
on my todo list for ages, it probably won't happen.

  write doc on libmidi++.a

In Driver:
  Find tester for SVR4
  Comment driver code better.
  Optimize realtime functions - this has already been done to a partial
extent.  Click calculations are now done are read and write time.


Long term:
  Write a graphical notation program based on tclmidi and/or libmidi++.a
That was why I rewrote tclmidi, wasn't it?
