Support guices @BindingAnnotation? or flag as an error?

Part of using @AutoFactory in a guice project is migrating all the binding annotations use the @Qualifier annotation instead of (or in addition to) @BindingAnnotation. It would be nice if @AutoFactory flagged this as an error (or if it just worked).

The current state is that it ignores @BindingAnnotation meaning that it may generate a factory that uses different bindings than the user intended.
