So, this class doesn't reopen a Cocoa class, it subclasses it. Same anyhow? The
real problem is that the class is instantiated as a side effect of nib loading,
and the only place I've been able to successfully set initial state is
awakeFromNib. I either can't, or don't know how to make the nib load process
call a DuplicateCounterTextField.initWithSomeCoolState method. My impression is
that awakeFromNib is a poor place for setting initial state because the order
in which awakeFromNib's are called is undefined (or is it?). Not to
overcomplicate things, but the controller needs to be able to tweak the state
of the control -- for example, to change the splitter regex.
Thanks for helping out here.
