Annotation NodeFieldsSignature enables the ControlSignatureProcessor annotation processor to issue a compile error if the user visitors' visit methods are not coded against the last nodes definitions.
The user nodes signatures are generated in the NodeConstants class,
the default visitors' visit methods are generated with the NodeFieldsSignature annotation, with the 3 values value(),
and the user visitors' visit methods can be annotated with the same annotation.
Note: the fully qualified name of this class is a parameter in the SupportedAnnotationTypes annotation in ControlSignatureProcessor.
