* A BListView displays a list of items the user can select and
* invoke. Each item is a kind of BListItem object. The BListView
* manages the layout of the list and the interaction with the user;
* it leaves the display of each item to the BListItem objects.
* A BListItem is not a view and draws only when called upon by
* the BListView.
