radio() public method

### Attributes: - value - Indicates the value when this radio button is checked. - label - boolean to indicate whether or not labels for widgets should be displayed. - 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. - 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.
