54  *  For any nonsingular iterator i:
55  *    i.node is the address of an element in the map array.  The
56  *      contents of i.node is a pointer to the beginning of a node.
57  *    i.first == *(i.node)
58  *    i.last  == i.first + node_size
59  *    i.cur is a pointer in the range [i.first, i.last).  NOTE:
60  *      the implication of this is that i.cur is always a dereferenceable
61  *      pointer, even if i is a past-the-end iterator.
62  *  Start and Finish are always nonsingular iterators.  NOTE: this means
63  *    that an empty deque must have one node, and that a deque
64  *    with N elements, where N is the buffer size, must have two nodes.
65  *  For every node other than start.node and finish.node, every element
66  *    in the node is an initialized object.  If start.node == finish.node,
67  *    then [start.cur, finish.cur) are initialized objects, and
68  *    the elements outside that range are uninitialized storage.  Otherwise,
69  *    [start.cur, start.last) and [finish.first, finish.cur) are initialized
70  *    objects, and [start.first, start.cur) and [finish.cur, finish.last)
71  *    are uninitialized storage.
72  *  [map, map + map_size) is a valid, non-empty range.
73  *  [start.node, finish.node] is a valid range contained within
74  *    [map, map + map_size).
75  *  A pointer in the range [map, map + map_size) points to an allocated node
76  *    if and only if the pointer is in the range [start.node, finish.node].
