For Dequeue lab:
Using the Dequeue interface in CITS2200:
e.g peekRight() returns an E
Stored in Object, when I get the item I cast the object to E
ie. return (E)queue
However I get a Unchecked cast from object to E warning. Google suggests suppressing
it, but it doesnt see like the correct way to do it. The error shows up on the
cssumbit near the top, even though its full marks.
