> Enhance Externalizer interface with methods for getTypeClasses(), getTypeClassNames() and getId() in favour of annotations.
> The reason for doing this is twofold:
> - The use of annotations makes it difficult for other apps to abstract the externalizer framework.
> - Runtime errors not caught at compilation time could arise from code like this where X and Y have no relationship:
> @Marshalls(typeClasses = Y.class, id = ExternalizerIds.XExternalizer)
> public class XExternalizer implements
> 		Externalizer<X> {
> In particular, code like this would maintain guarantees between classes externalized and return of readObject(): 
> List<Class<? extends T>> getTypeClasses();
