Increments or decrements the iterator. Inverse operations are applied to the underlying operator because of the reverse order.

1-2) Pre-increments or pre-decrements by one respectively.
3-4) Post-increments or post-decrements by one respectively.
5-6) Returns an iterator which is advanced by `n` or `-n` positions respectively.
7-8) Advances the iterator by `n` or `-n` positions respectively.

### [edit] Return value

1-2) *this
3-4) a copy of *this that was made before the change
5-6) reverse_iterator(base()-n) or reverse_iterator(base()+n) respectively.
7-8) *this
