Needle is a dependency injection/inversion of control container for Ruby, employing many of Ruby's best idioms.

This release allows portions of Needle's internals to be customized, including custom namespace, interceptor, and definition context implementations. See chapter 9 of the users manual for details.

This release also allows Needle::Registry to be given a parent and a name. Previous versions enforced the registry's place at the root of a container hierarchy.
