/**
 * RadioSelectWidget is a {@link OO.ui.SelectWidget select widget} that contains radio
 * options and is used together with OO.ui.RadioOptionWidget. The RadioSelectWidget provides
 * an interface for adding, removing and selecting options.
 * Please see the [OOjs UI documentation on MediaWiki][1] for more information.
 *
 *     @example
 *     // A RadioSelectWidget with RadioOptions.
 *     var option1 = new OO.ui.RadioOptionWidget( {
 *         data: 'a',
 *         label: 'Selected radio option'
 *     } );
 *
 *     var option2 = new OO.ui.RadioOptionWidget( {
 *         data: 'b',
 *         label: 'Unselected radio option'
 *     } );
 *
 *     var radioSelect=new OO.ui.RadioSelectWidget( {
 *         items: [ option1, option2 ]
 *      } );
 *
 *     // Select 'option 1' using the RadioSelectWidget's selectItem() method.
 *     radioSelect.selectItem( option1 );
 *
 *     $( 'body' ).append( radioSelect.$element );
