Two struct objects with their own Redblack trees seem to be incorrectly joining trees values?

You would *think* that this would create a new instance every 
time that the struct is instantiated.

Unfortunately what it does in fact do, is create a RedBlackTree 
instance *at compiletime*, emit it into the binary, and assign 
its reference as the default initializer of the `rbt` field.

I think probably the easiest fix is make Bag a class and assign 
`new RedBlackTree` in the constructor.
