* Replaces the identification of "evaluate" methods by a custom
  annotation that takes the parent Evaluator class as its argument to
  differentiate between evaluate methods across Evaluator boundaries.
  This is required by the binding mechanism of Guice.
* Not yet ported Evaluators are not aligned with the new Annotation.
* Bug Fixes:
** Register the MappingConstraintEvaluator.
** Correct the constructor of the MappingConstraintEvaluator.
** Fix parameter list of its evaluate method.
