/*

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.
