For some reason RedBlackTree doesn't have a length property. From what I
understand of red black trees, it should be able to easily keep track of its
length and have a length property which is O(1). But it doesn't have that right
now. Instead, you have to use walkLength, which is O(n). A length property
which is O(1) should be added to RedBlackTree.
