Initializer
- `Option(String? argName = null, {String*}? choices = null, String? defaultValue = null, String? description = null, Boolean? flag = null, Boolean? help = null, Boolean? hidden = null, String? longName = null, Boolean? multiValued = null, String? name = null, Boolean? required = null, String? shortName = null, Boolean? singleValued = null)` Parameters: `argName = null` Sets te arg name for this option. `choices = null` Sets the list of values accepted by this option. If the value set by the user does not match once of these values, a `io.vertx.core.cli.InvalidValueException` exception is thrown. `defaultValue = null` Sets the default value of this option `description = null` Sets te description of this option. `flag = null` Configures the current Option to be a flag. It will be evaluated to `true` if it's found in the command line. If you need a flag that may receive a value, use, in this order: ``
      option.setFlag(true).setSingleValued(true)
`help = null` Sets whether or not this option is a “help” option `hidden = null` Sets whether or not this option should be hidden `longName = null` Sets the long name of this option. `multiValued = null` Sets whether or not this option can receive several values. `name = null` `required = null` Sets whether or not this option is mandatory. `shortName = null` Sets the short name of this option. `singleValued = null` Sets whether or not this option can receive a value.
