You can observe the "arrangedObjects" property of the array controller, or you
can observe the same array property in your data model that your
arrayController is bound to (its "contentArray").

All views know what window they're in ([view window]) so it's easy to do both
#1 and #2 given just a pointer to the view controller and a pointer to the
array controller._______________________________________________
