令 current_ 为底层迭代器数组，并且 Base 为底层视图的）（可能有 const 限定）类型。

1,2) 返回递增 n 的迭代器 i。 等价于 auto r = i; r += n; return r;

3) 返回递减 n 的迭代器 i。 等价于 auto r = i; r -= n; return r;

4) 返回两个迭代器的 i 之间的 j 距离。 等价于 return i.current_.back() - j.current_.back();

这些函数对通常无限定或有限定查找不可见，而只能在 adjacent_view::iterator<Const> 为参数的关联类时由实参依赖查找找到。

参数

i, j	-	迭代器
n	-	相对于当前的位置

返回值

1-2) 增加的迭代器

3) 减小的迭代器

4) 两个迭代器之间的距离
