<blockquote>
This class is a subclass of NSTableView which provides the
user with a way to display tree structured data in an
outline format. It is particularly useful for show
hierarchical data such as a class inheritance tree
or any other set of relationships. <br /> NB. While it its
illegal to have the same item in the view more than once,
it is possible to have multiple equal items since tests for
pointer equality are used rather than calls to the
-isEqual:
method.
