The number can be added to a pasteboard. Or if dragging more than one
object, NSNumbers can be added to an NSArray, and the array written to
the pasteboard.
You don't have to actually pass the data through the pasteboard if
it's only moving it from one place to another within your app. You
could just store the objects in some global (or better, class static)
and then fetch them when you paste.
