Copperbox revision 119.
More work on Chords - again this work is partial so is currently comment out. However it revealed another problem with intervals - I couldn't count up from one pitch to another with an arithmetic distance. So I've added a new function, to do this:
arithmeticStep :: Pitch -> Int -> Pitch
This has shown up a problem with the Pitch instance of`addSemi` whereby the pitch spelling goes wrong. I haven't correct this at the moment as I'm not sure if my obvious fix is correct (the obvious fix is to keep the pitch letter the same and simply alter the accidental).
