Subject: Root parent link

As of now the parent link in root is set to null. Thus calling cd ..
inside root will throw a null pointer exception. I can only think of
two ways of dealing with it. One would be to set root's parent equal to
itself thus calling cd .. will not cause a problem, Unfortunately I
don't know if any traversals depend on that link being null. The other
way would be to just catch the null pointer exception in the cd function
and continue running the code as is. The second one seems less painful
and least likely to effect other parts of the code. Is this something
we need to worry about at all?
