+
+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.
