/**
 * 
 * A class for validating a form which may have discrepancy notes attached
 * 
 * This class executes the rule that if a form field has a discrepancy note
 * attached, it should not be validated. The mechanism is via the
 * <code>validate(String, Validation)</code> method. When this method is
 * executed by this class, the class checks to see if a discrepancy note is
 * available for the field. If so, it takes no action. Otherwise, it executes
 * the validation using the superclass's validate method.
 * 
 * You can use this class exactly as you use the Validator class. Simple declar
 * objects to be DiscrepancyValidator, rather than Validator, objects, and
 * provide the appropriate FormDiscrepancyNotes object in the constructor.
