We now have a C++ red-black tree implementation that implements standard template library compatible APIs while compiling 10x faster than libcxx. It's not as beautiful as the red-black tree implementation in Plinko but this will get the job done and the test proves it upholds all invariants This change also restores CheckForMemoryLeaks() support and fixes a real actual bug I discovered with Doug Lea's dlmalloc_inspect_all() function.
