Title: Allow unordered_map_concurrent caller to specify a custom bin container

I don't have a use for this (other than some things I've been testing that aren't ready for prime time).

But this tweaks the unordered_map_concurrent template to allow you to override the underlying container type that's used for the bins. By default, it's an unordered_map.
