> Patch to configuration to:
> * Update documentation to match code
> * Make configurations hierarchical
> * Remove global REGISTRY of configurations
> * Adding global default does not reload child configurations
> * (Eventually) make properly thread-safe
> * Allow well-behaved overriding with nulls
> * Allow future satisfaction of ticket 5708 (with which I agree, but Doug does not).
