In your scenario -- where the list is "really" flat but displayed
hierarchically for esthetic reasons -- the array approach is fine.

If you're *already* using these OvItem objects, then I'd say it's worth doing
this. It makes things a bit clearer when you (or someone else) return to the
code in the future. It would probably also allow you to simplify your
'outlineView:objectValueForTableColumn:byItem:' method a bit.
