Advances or decrements the iterator .

Let current_ and last_ele_ be the underlying iterators to the begin and end of the sliding window.

1) Equivalent to: 
current_ = ranges::next(current_);
last_ele_ = ranges::next(last_ele_); // if last_ele_ is present
return *this;
Before the invocation, the current_ and last_ele_ (if present) must be incrementable.
2) Equivalent to: auto tmp = * this ; ++* this ; return tmp ;
3) Equivalent to: 
current_ = ranges::prev(current_);
last_ele_ = ranges::prev(last_ele_); // if last_ele_ is present
return *this;
Before the invocation, the current_ and last_ele_ (if present) must be decrementable.
4) Equivalent to: auto tmp = * this ; --* this ; return tmp ;
5) Equivalent to: 
current_ = current_ + n;
last_ele_ = last_ele_ + n; // if last_ele_ is present
return *this;
Before the invocation, the expressions current_ + n and last_ele_ + n (if last_ele_ is present) must have well-defined behavior.
6) Equivalent to: 
current_ = current_ - n;
last_ele_ = last_ele_ - n; // if last_ele_ is present
return *this;
Before the invocation, the expressions current_ - n and last_ele_ - n (if last_ele_ is present) must have well-defined behavior.
