Interface supplying the information necessary to describe an introduction.

IntroductionAdvisors must implement this interface. If an Advice implements this, it may be used as an introduction without an IntroductionAdvisor. In this case, the advice is self-describing, providing not only the necessary behavior, but describing the interfaces it introduces.
