SpreadSheet.newFile() will clear all SpreadSheet cells.
If you want to clear them all without asking for user
confirmation, call SpreadSheet.newFile(false). However,
that method is protected, so you'll either need to hack
the SpreadSheet and make it public, or else define an
extension of the SpreadSheet that calls it for you.
