-Red-black tree class, designed for use in implementing STL
-associative containers (set, multiset, map, and multimap). The
-insertion and deletion algorithms are based on those in Cormen,
-Leiserson, and Rivest, Introduction to Algorithms (MIT Press, 1990),
-except that
-
-(1) the header cell is maintained with links not only to the root
-but also to the leftmost node of the tree, to enable constant time
-begin(), and to the rightmost node of the tree, to enable linear time
-performance when used with the generic set algorithms (set_union,
-etc.);
-
-(2) when a node being deleted has two children its successor node is
-relinked into its place, rather than copied, so that the only
-iterators invalidated are those referring to the deleted node.
