     * @description
     * `<InstantSearch>` is the root component of all React InstantSearch implementations.
     * It provides all the connected components (aka widgets) a means to interact
     * with the searchState.
     * @kind widget
     * @name <InstantSearch>
     * @requirements You will need to have an Algolia account to be able to use this widget.
     * [Create one now](https://www.algolia.com/users/sign_up).
     * @propType {string} indexName - Main index in which to search.
     * @propType {boolean} [refresh=false] - Flag to activate when the cache needs to be cleared so that the front-end is updated when a change occurs in the index.
     * @propType {object} [searchClient] - Provide a custom search client.
     * @propType {func} [onSearchStateChange] - Function to be called everytime a new search is done. Useful for [URL Routing](guide/Routing.html).
     * @propType {object} [searchState] - Object to inject some search state. Switches the InstantSearch component in controlled mode. Useful for [URL Routing](guide/Routing.html).
     * @propType {func} [createURL] - Function to call when creating links, useful for [URL Routing](guide/Routing.html).
     * @propType {SearchResults|SearchResults[]} [resultsState] - Use this to inject the results that will be used at first rendering. Those results are found by using the `findResultsState` function. Useful for [Server Side Rendering](guide/Server-side_rendering.html).
     * @propType {number} [stalledSearchDelay=200] - The amount of time before considering that the search takes too much time. The time is expressed in milliseconds.
     * @propType {{ Root: string|function, props: object }} [root] - Use this to customize the root element. Default value: `{ Root: 'div' }`
     * @example
     * import React from 'react';
     * import algoliasearch from 'algoliasearch/lite';
     * import { InstantSearch, SearchBox, Hits } from 'react-instantsearch-dom';
     *
     * const searchClient = algoliasearch(
     *   'latency',
     *   '6be0576ff61c053d5f9a3225e2a90f76'
     * );
     *
     * const App = () => (
     *   <InstantSearch
     *     searchClient={searchClient}
     *     indexName="instant_search"
     *   >

    /**
     * A breadcrumb is a secondary navigation scheme that allows the user to see where the current page
     * is in relation to the website or web application’s hierarchy.
     * In terms of usability, using a breadcrumb reduces the number of actions a visitor needs to take in
     * order to get to a higher-level page.
     *
     * If you want to select a specific refinement for your Breadcrumb component, you will need to
     * use a [Virtual Hierarchical Menu](https://community.algolia.com/react-instantsearch/guide/Virtual_widgets.html)
     * and set its defaultRefinement that will be then used by the Breadcrumb.
     *
     * @name Breadcrumb
     * @kind widget
     * @requirements Breadcrumbs are used for websites with a large amount of content organised in a hierarchical manner.
     * The typical example is an e-commerce website which has a large variety of products grouped into logical categories
     * (with categories, subcategories which also have subcategories).To use this widget, your attributes must be formatted in a specific way.
     *
     * Keep in mind that breadcrumbs shouldn’t replace effective primary navigation menus:
     * it is only an alternative way to navigate around the website.
     *
     * If, for instance, you would like to have a breadcrumb of categories, objects in your index
     * should be formatted this way:
     *
     * ```json
     * {
     *   "categories.lvl0": "products",
     *   "categories.lvl1": "products > fruits",
     *   "categories.lvl2": "products > fruits > citrus"
     * }
     * ```
     *
     * It's also possible to provide more than one path for each level:
     *
     * ```json
     * {
     *   "categories.lvl0": ["products", "goods"],
     *   "categories.lvl1": ["products > fruits", "goods > to eat"]
     * }
     * ```
     *
     * All attributes passed to the `attributes` prop must be present in "attributes for faceting"
     * on the Algolia dashboard or configured as `attributesForFaceting` via a set settings call to the Algolia API.
     *
     * @propType {array.<string>} attributes - List of attributes to use to generate the hierarchy of the menu. See the example for the convention to follow
     * @propType {node} [separator='>'] -  Symbol used for separating hyperlinks
     * @propType {string} [rootURL=null] - The originating page (homepage)
     * @propType {function} [transformItems] - Function to modify the items being displayed, e.g. for filtering or sorting them. Takes an items as parameter and expects it back in return
     * @themeKey ais-Breadcrumb - the root div of the widget
     * @themeKey ais-Breadcrumb--noRefinement - the root div of the widget when there is no refinement
     * @themeKey ais-Breadcrumb-list - the list of all breadcrumb items
     * @themeKey ais-Breadcrumb-item - the breadcrumb navigation item
     * @themeKey ais-Breadcrumb-item--selected - the selected breadcrumb item
     * @themeKey ais-Breadcrumb-separator - the separator of each breadcrumb item
     * @themeKey ais-Breadcrumb-link - the clickable breadcrumb element
     * @translationKey rootLabel - The root's label. Accepts a string
     * @example
     * import React from 'react';
     * import algoliasearch from 'algoliasearch/lite';
     * import { Breadcrumb, InstantSearch, HierarchicalMenu } from 'react-instantsearch-dom';
     *
     * const searchClient = algoliasearch(
     *   'latency',
     *   '6be0576ff61c053d5f9a3225e2a90f76'
     * );
     *
     * const App = () => (
     *   <InstantSearch
     *     searchClient={searchClient}

    /**
     * The hierarchical menu lets the user browse attributes using a tree-like structure.
     *
     * This is commonly used for multi-level categorization of products on e-commerce
     * websites. From a UX point of view, we suggest not displaying more than two levels deep.
     *
     * @name HierarchicalMenu
     * @kind widget
     * @requirements To use this widget, your attributes must be formatted in a specific way.
     * If you want for example to have a hiearchical menu of categories, objects in your index
     * should be formatted this way:
     *
     * ```json
     * [{
     *   "objectID": "321432",
     *   "name": "lemon",
     *   "categories.lvl0": "products",
     *   "categories.lvl1": "products > fruits",
     * },
     * {
     *   "objectID": "8976987",
     *   "name": "orange",
     *   "categories.lvl0": "products",
     *   "categories.lvl1": "products > fruits",
     * }]
     * ```
     *
     * It's also possible to provide more than one path for each level:
     *
     * ```json
     * {
     *   "objectID": "321432",
     *   "name": "lemon",
     *   "categories.lvl0": ["products", "goods"],
     *   "categories.lvl1": ["products > fruits", "goods > to eat"]
     * }
     * ```
     *
     * All attributes passed to the `attributes` prop must be present in "attributes for faceting"
     * on the Algolia dashboard or configured as `attributesForFaceting` via a set settings call to the Algolia API.
     *
     * @propType {array.<string>} attributes - List of attributes to use to generate the hierarchy of the menu. See the example for the convention to follow.
     * @propType {boolean} [showMore=false] - Flag to activate the show more button, for toggling the number of items between limit and showMoreLimit.
     * @propType {number} [limit=10] -  The maximum number of items displayed.
     * @propType {number} [showMoreLimit=20] -  The maximum number of items displayed when the user triggers the show more. Not considered if `showMore` is false.
     * @propType {string} [separator='>'] -  Specifies the level separator used in the data.
     * @propType {string} [rootPath=null] - The path to use if the first level is not the root level.
     * @propType {boolean} [showParentLevel=true] - Flag to set if the parent level should be displayed.
     * @propType {string} [defaultRefinement] - the item value selected by default
     * @propType {function} [transformItems] - Function to modify the items being displayed, e.g. for filtering or sorting them. Takes an items as parameter and expects it back in return.
     * @themeKey ais-HierarchicalMenu - the root div of the widget
     * @themeKey ais-HierarchicalMenu-noRefinement - the root div of the widget when there is no refinement
     * @themeKey ais-HierarchicalMenu-searchBox - the search box of the widget. See [the SearchBox documentation](widgets/SearchBox.html#classnames) for the classnames and translation keys of the SearchBox.
     * @themeKey ais-HierarchicalMenu-list - the list of menu items
     * @themeKey ais-HierarchicalMenu-list--child - the child list of menu items
     * @themeKey ais-HierarchicalMenu-item - the menu list item
     * @themeKey ais-HierarchicalMenu-item--selected - the selected menu list item
     * @themeKey ais-HierarchicalMenu-item--parent - the menu list item containing children
     * @themeKey ais-HierarchicalMenu-link - the clickable menu element
     * @themeKey ais-HierarchicalMenu-label - the label of each item
     * @themeKey ais-HierarchicalMenu-count - the count of values for each item
     * @themeKey ais-HierarchicalMenu-showMore - the button used to display more categories
     * @themeKey ais-HierarchicalMenu-showMore--disabled - the disabled button used to display more categories
     * @translationKey showMore - The label of the show more button. Accepts one parameter, a boolean that is true if the values are expanded
