Implement ExtendedList interface that extends List interface
and supports ConditionalIterator.
Your implementation should pass all tests.
Run ExtendedListTest to check all possible tests.
Try to uncomment line 86 and comment lines 81-84 to perform
tests on Array list.
Also create your own unit tests to for functionality you have implemented.
Implement ContidionalIterator interface that extends Iterator interface.
ConditionalIterator should work with proposed Filter objects
to identify if element in collection should be iterated or not.
Take look at ExtendedListTest.ConditionalIteratorTests for additional information about possible filters.
Also create your own unit tests to for functionality you have implemented.
