Perl implementation of Red/Black tree, a balanced tree

Tree::RedBlack is a demonstration package, showing the performance differences between different methods of data storage and accessing. It contains a perl implementation of the Red/Black tree algorithm found in the book "Algorithms", by Cormen, Leiserson & Rivest (more commonly known as "CLR" or "The White Book"). A Red/Black tree is a binary tree which remains "balanced"- that is, the longest length from root to a node is at most one more than the shortest such length. It is fairly efficient; no operation takes more than O(lg(n)) time.

An example perl script is contained in the documentation directory, which would show the different run times using hash table, linear or tree structure.
