HNotate

Copperbox revision 252.

I've added a rudimentary interface to Haskore. One of the simplest examples in Haskore produces equivalent output (t251), but more complex examples produce musical gibberish (Children's Song 6, Stars and Stripes Forever).

Working with Haskore's trills is going to be difficult as they are rendered directly to notes (with short durations). In Abc and LilyPond grace notes, which would accommodate trills, are a special case in that they aren't counted in a bars duration.
