[JW Lua] Vocal compass

[Mr.Pat]

Here's my first attempt. My work is with choral music so this plugin applies
to choral scores. It scans the selected region to find the highest, lowest,
and mean notes in the selected staves. It then displays them in the first
measure of the staff. It assumes that there is at least one note in the
first measure already. All of my templates are set up like that. The plugin
works as it is, but I think there is a more efficient way to get the notes
placed in the first measure. Suggestions welcomed.
