struct std::_Deque_iterator< _Tp, _Ref, _Ptr >"
A deque::iterator\&. 

Quite a bit of intelligence here\&. Much of the functionality of deque is actually passed off to this class\&. A deque holds two of these internally, marking its valid range\&. Access to elements is done as offsets of either of those two, relying on operator overloading in this class\&.
.PP
All the functions are op overloads except for _M_set_node\&.

Prepares to traverse new_node\&. Sets everything except _M_cur, which should therefore be set by the caller immediately afterwards, based on _M_first and _M_last\&.
