I am trying to figure out how I can create a FinaleScript to do the following:

Create a new staff named "Cello Controller"
Set it's first clef to be the octave bass clef
Set it to have an independent key signature
Then set it's key signature to C major

I have figured out how to create the staff with the
   create staff "Cello Controller" command
but I am having trouble trying to figure out how to get the other 3 actions to work
