/**
* ButtonWidget is a generic widget for buttons. A wide variety of looks,
* feels, and functionality can be customized via the class’s configuration options
* and methods. Please see the [OOjs UI documentation on MediaWiki] [1] for more information
* and examples.
*
* [1]: https://www.mediawiki.org/wiki/OOjs_UI/Widgets/Buttons_and_Switches
*
* @example
* // A button widget
* var button = new OO.ui.ButtonWidget( {
* label: 'Button with Icon',
* icon: 'remove',
* iconTitle: 'Remove'
* } );
* $( 'body' ).append( button.$element );
*
* NOTE: HTML form buttons should use the OO.ui.ButtonInputWidget class.
*
* @class
* @extends OO.ui.Widget
* @mixins OO.ui.ButtonElement
* @mixins OO.ui.IconElement
* @mixins OO.ui.IndicatorElement
* @mixins OO.ui.LabelElement
* @mixins OO.ui.TitledElement
* @mixins OO.ui.FlaggedElement
* @mixins OO.ui.TabIndexedElement
*
* @constructor
* @param {Object} [config] Configuration options
* @cfg {string} [href] Hyperlink to visit when the button is clicked.
* @cfg {string} [target] The frame or window in which to open the hyperlink.
* @cfg {boolean} [noFollow] Search engine traversal hint (default: true)
