I wrote a little diatonic transposition script but I don't know how to
deal with split strings so it does not deal with chords yet. I am
attaching it here. It is based off the diatonic transposition item
called "Third". This one has a pop-up dialog asking the interval of
transposition. 

When I write one that does a real transposition should the key signature
be changed or remain the same?
