Creates a set of radio widgets.

### Attributes:

- `value` - Indicates the value when this radio button is checked.
- `label` - Either `false` to disable label around the widget or an array of attributes for
the label tag. `selected` will be added to any classes e.g. `'class' => 'myclass'` where widget
is checked
- `hiddenField` - boolean to indicate if you want the results of radio() to include
a hidden input with a value of ''. This is useful for creating radio sets that are non-continuous.
- `disabled` - Set to `true` or `disabled` to disable all the radio buttons. Use an array of
values to disable specific radio buttons.
- `empty` - Set to `true` to create an input with the value '' as the first option. When `true`
the radio label will be 'empty'. Set this option to a string to control the label value.

@param string $fieldName Name of a field, like this "modelname.fieldname"
@param array|\Traversable $options Radio button options array.
