The whiteboard implementation must create dynamic classes for each extension service to allow multiple instances of the same class to be registered. The existing generics handling was limited, and could not correctly represent unbound type variables, wildcards, nested generics, or reification of variables declared in super types. This commit enhances the generics processing in an attempt to cover all cases. Fixes #39

Fix issues with generics in extension services

I identified a missing test case where a Type Variable changes name in the generics declaration of an intermediate super class, and also where the Type Variable use is nested inside another generic declaration. Once added these tests showed up some further weaknesses which I have attempted to fix by establishing a context mapping of contract interface to implementing type and type to super type. This constrains the search through the type information and ensures that we only match type information that is relevant in the current context.
