public class IlpListModelSorter extends AbstractListModel implements ListModel
ListModel implementation is used to sort the items
in a list.
It encapsulates the ListModel to be sorted,
as described in the decoration design pattern.
IlpListModelSorter listens to the model it encapsulates and forwards
the model changes to its own listeners according to the sorting
parameters.
