/**
*
* Field Validator that checks if the short specified is within a certain range.
*
*
*
*
*
* - fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
* - min - the minimum value (if none is specified, it will not be checked)
* - max - the maximum value (if none is specified, it will not be checked)
* - parse - if set to true, minExpression and maxExpression will be evaluated to find min/max
* - minExpression - expression to calculate the minimum value (if none is specified, it will not be checked)
* - maxExpression - expression to calculate the maximum value (if none is specified, it will not be checked)
*
*
* 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.
*
*
*
* Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!
