/**
* Implementation of an immutable SortedMap using a Left-leaning
* Red-Black Tree, adapted from the implementation in Mugs
* (http://mads379.github.com/mugs/) by Mads Hartmann Jensen
* (mads379@gmail.com).
*
* Original paper on Left-leaning Red-Black Trees:
* http://www.cs.princeton.edu/~rs/talks/LLRB/LLRB.pdf
*
* Invariant 1: No red node has a red child
* Invariant 2: Every leaf path has the same number of black nodes
* Invariant 3: Only the left child can be red (left leaning)
