Increments or decrements the iterator.

Let inner_ be the underlying iterator and Base be the exposition-only member type.

Equivalent to:

1) ++inner_; return *this;

2) ++*this;

3) auto tmp = *this; ++*this; return tmp;

4) --inner_; return *this;

5) auto tmp = *this; --*this; return tmp;

6) inner_ += n; return *this;

7) inner_ -= n; return *this;

position relative to current location

1,4,6,7) *this

2) (none)

3,5) a copy of *this that was made before the change
