org.geotools.validation.attributes.UniqueFIDValidation
Ensure every feature has a unique Feature Id specified by uniqueID.
Please note that featureIDs are not attributes. Attributes may be checked with the UniquityValidation class.

The FeatureTypes it checks against are defined by typeNames[]. If a duplicate ID is detected, an error message returned via a Validation Result used as a visitor in the validation() method.

Example Use:
```
 UniqueFIDIntegrityValidation x = new UniqueFIDIntegrityValidation("uniqueFID_road", "Checks if each feature has a unique ID", new String[] {"road", "river"}, "FID"); x.validate(); 
```

        // the visitor
        RoadValidationResults validationResults = new RoadValidationResults();


        UniqueFIDValidation validator = new UniqueFIDValidation();
        validator.setName("isValidRoad");
        validator.setDescription("Tests to see if a road is valid");
        validator.setTypeRef( "*" );
        validationResults.setValidation(validator);


        HashMap layers = new HashMap();
        layers.put("road", store.getFeatureSource("road"));
        layers.put("river", store.getFeatureSource("river"));


        assertTrue(validator.validate(layers, null, validationResults)); // validate will return true
    }
