Implement a Validator Resolver
As a convenience function (eg. in the Property Mapper) we need a resolver which is able to find a validator for the given object. The interface of T3_Framework_Validation_ValidatorResolver could be as simple as:
public function resolveValidatorName($targetObject); public function resolveValidator($targetObject);
the first method returns the component name (or NULL if no validator could be found) and the second method returns an actual validator object.
