* Only one list index can be selected at a time. In this mode,
* {@code setSelectionInterval} and {@code addSelectionInterval} are
* equivalent, both replacing the current selection with the index
* represented by the second argument (the "lead").
* <li>{@code ListSelectionModel.SINGLE_INTERVAL_SELECTION} -
* Only one contiguous interval can be selected at a time.
* In this mode, {@code addSelectionInterval} behaves like
* {@code setSelectionInterval} (replacing the current selection},
* unless the given interval is immediately adjacent to or overlaps
* the existing selection, and can be used to grow the selection.
* <li>{@code ListSelectionModel.MULTIPLE_INTERVAL_SELECTION} -
* In this mode, there's no restriction on what can be selected.
* This mode is the default.
