/**
 * Class Tribe__Field_Conditional
 *
 * A work-around for PHP 5.2 lack of closure support to wrap
 *
 * Example usage: in the context of the definition of a list of fields to be fed to the Tribe__Settings class:
 *
 *      $fields = array(
 *          'foo' => array(
 *              'type' => 'checkbox_bool',
 *              // ...
 *          ),
 *          'bar' => array(
 *              'type' => 'text'
 *              'validate_if' => new Tribe__Field_Conditional( 'foo', 'tribe_is_truthy' )
 *              'conditional' => tribe_is_truthy( tribe_get_option( 'foo' ) ),
 *              // ...
 *          ),
 *      );
 *
 * The above will modify the validation logic to make it so that the field will not be validated if
 * the parent (`foo` in the example) is not "truthy".
 * If you need to hide/show the field conditionally use the `conditional` attribute of the field.
