/**
* FieldsetLayouts are composed of one or more {@link OO.ui.FieldLayout FieldLayouts},
* which each contain an individual widget and, optionally, a label. Each Fieldset can be
* configured with a label as well. For more information and examples,
* please see the [OOjs UI documentation on MediaWiki][1].
*
* @example
* // Example of a fieldset layout
* var input1 = new OO.ui.TextInputWidget( {
* placeholder: 'A text input field'
* } );
*
* var input2 = new OO.ui.TextInputWidget( {
* placeholder: 'A text input field'
* } );
*
* var fieldset = new OO.ui.FieldsetLayout( {
* label: 'Example of a fieldset layout'
* } );
*
* fieldset.addItems( [
* new OO.ui.FieldLayout( input1, {
* label: 'Field One'
* } ),
* new OO.ui.FieldLayout( input2, {
* label: 'Field Two'
* } )
* ] );
* $( 'body' ).append( fieldset.$element );

* @extends OO.ui.Layout
* @mixes OO.ui.mixin.IconElement

* @mixes OO.ui.mixin.GroupElement
*
* @constructor
* @param {Object} [config] Configuration options
* @param {OO.ui.FieldLayout[]} [config.items] An array of fields to add to the fieldset. See OO.ui.FieldLayout for more information about fields.
* @param {string|OO.ui.HtmlSnippet} [config.help] Help text. When help text is specified, a "help" icon will appear
* in the upper-right corner of the rendered field; clicking it will display the text in a popup.
* For important messages, you are advised to use `notices`, as they are always shown.
* @param {jQuery} [config.$overlay] Passed to OO.ui.PopupButtonWidget for help popup, if `help` is given.
* See <https://www.mediawiki.org/wiki/OOjs_UI/Concepts#Overlays>.
