/* Class invariants:
 *  For any nonsingular iterator i:
 *    i.node is the address of an element in the map array.  The
 *      contents of i.node is a pointer to the beginning of a node.
 *    i.first == *(i.node) 
 *    i.last  == i.first + node_size
 *    i.cur is a pointer in the range [i.first, i.last).  NOTE:
 *      the implication of this is that i.cur is always a dereferenceable
 *      pointer, even if i is a past-the-end iterator.
 *  Start and Finish are always nonsingular iterators.  NOTE: this means
 *    that an empty deque must have one node, and that a deque
 *    with N elements, where N is the buffer size, must have two nodes.
 *  For every node other than start.node and finish.node, every element
 *    in the node is an initialized object.  If start.node == finish.node,
 *    then [start.cur, finish.cur) are initialized objects, and
 *    the elements outside that range are uninitialized storage.  Otherwise,
 *    [start.cur, start.last) and [finish.first, finish.cur) are initialized
 *    objects, and [start.first, start.cur) and [finish.cur, finish.last)
 *    are uninitialized storage.
 *  [map, map + map_size) is a valid, non-empty range.  
 *  [start.node, finish.node] is a valid range contained within 
 *    [map, map + map_size).  
 *  A pointer in the range [map, map + map_size) points to an allocated node
 *    if and only if the pointer is in the range [start.node, finish.node].
 */


/*
 * In previous versions of deque, node_size was fixed by the 
 * implementation.  In this version, however, users can select
 * the node size.  Deque has three template parameters; the third,
 * a number of type size_t, is the number of elements per node.
 * If the third template parameter is 0 (which is the default), 
 * then deque will use a default node size.
 *
 * The only reason for using an alternate node size is if your application
 * requires a different performance tradeoff than the default.  If,
 * for example, your program contains many deques each of which contains
 * only a few elements, then you might want to save memory (possibly
 * by sacrificing some speed) by using smaller nodes.
 *
 * Unfortunately, some compilers have trouble with non-type template 
 * parameters; stl_config.h defines __STL_NON_TYPE_TMPL_PARAM_BUG if
 * that is the case.  If your compiler is one of them, then you will
 * not be able to use alternate node sizes; you will have to use the
 * default value.
