Abstract class for testing the ListIterator interface.
This class provides a framework for testing an implementation of ListIterator.
Concrete subclasses must provide the list iterator to be tested.
They must also specify certain details of how the list iterator operates by
overriding the supportsXxx() methods if necessary.
