Fixed some typos and invalid coloring in PingPong benchmark
Add Immutable AVL Trees

Originally from http://justinmchase.com/2011/12/13/immutable-avl-tree-in-c/
Add ChildrenContainer

To use the immutable avl trees ActorRef must be IComparable so I implemented that for ActorRef and ActorPath
Add CAS helper methods for transforming values atomically
Switch to use ChildrenContainer in ActorCell
