Any plans to support child or cloned containers?

[GrantOllis]

A feature that would be extremely useful would be extremely useful would be to support the creation of child or cloned containers. A child container is more complex, being an empty container with a reference to a parent container and walking up the hierarchy as it tries to resolve types, but a clone would just duplicate existing bindings at the point it was cloned and then set itself as the Container object binding in place of the original container.

The use case for this is to allow for a "scoped" container to be created. For example when handling a HTTP request objects like a context.Context generated by a HTTP request, as well as the Request and ResponseWriter could be populated to a child/clone container while handling the request and then the Call method could be used to populate required Classes for a handler method.
