/**
 * <!-- START SNIPPET: javadoc -->
 * Field Validator that checks if the long specified is within a certain range.
 * <!-- END SNIPPET: javadoc -->
 *
 *
 * <!-- START SNIPPET: parameters -->
 * <ul>
 * 		<li>fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required</li>
 *      <li>min - the minimum value (if none is specified, it will not be checked) </li>
 *      <li>max - the maximum value (if none is specified, it will not be checked) </li>
 *      <li>parse - if set to true, minExpression and maxExpression will be evaluated to find min/max</li>
 *      <li>minExpression - expression to calculate the minimum value (if none is specified, it will not be checked) </li>
 *      <li>maxExpression - expression to calculate the maximum value (if none is specified, it will not be checked) </li>
 * </ul>
 *
 * You can either use the min / max value or minExpression / maxExpression (when parse is set to true) -
 * using expression can be slightly slower, see the example below.
 * <!-- END SNIPPET: parameters -->
 *
 * <!-- START SNIPPET: parameters-warning -->
 * Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!
