=====rotate=====
Syntax:

<code>
    #include <algorithm>
    void rotate( forward_iterator start, forward_iterator middle, forward_iterator end );
</code>

The rotate() algorithm moves the elements in the range [start,end) such that
the middle element is now where start used to be, (middle+1) is now at
(start+1), etc.

rotate() runs in [[/complexity|linear time]].
