Add option to not overwrite default Staff context
When writing sheet music, I would like to be able to write most the staves with traditional notation, but include one or a few parts written in Clairnote (I'm interested in learning Clairnote, but I doubt the rest of my band is). The current script is rather invasive; if I include clairnote.ly then I have to go through all the parts and replacing Staff with TradStaff. It would be nice to have a mode where I can instead include the file and just add a new part using a ClairStaff or something.
