 *
 * Import the validator into your component:
 *
 *  `import ExclusionValidator from 'utils/validations/exclusion'`
 *
 * Validate the value is not included in the list, pass an array in the param disallowedValues:
 *
 *  e.g.
 *
 *  `<TextArea validations={ [new ExclusionValidator({ disallowedValues: ['foo', 'bar'] })] }/>`
 *
 * would validate that the value of the text field is not either 'foo' or 'bar'.
