/**
 * `<vaadin-grid>` is a free, high quality data grid / data table Web Component. The content of the
 * the grid can be populated in two ways: imperatively by using renderer callback function and
 * declaratively by using Polymer's Templates.
 *
 * ### Quick Start
 *
 * Start with an assigning an array to the [`items`](#/elements/vaadin-grid#property-items) property to visualize your data.
 *
 * Use the [`<vaadin-grid-column>`](#/elements/vaadin-grid-column) element to configure the grid columns. Set `path` and `header`
 * shorthand properties for the columns to define what gets rendered in the cells of the column.
 *
 * #### Example:
 * ```html
 * <vaadin-grid>
 *   <vaadin-grid-column path="name.first" header="First name"></vaadin-grid-column>
 *   <vaadin-grid-column path="name.last" header="Last name"></vaadin-grid-column>
 *   <vaadin-grid-column path="email"></vaadin-grid-column>
 * </vaadin-grid>
 * ```
 *
 * For custom content `vaadin-grid-column` element provides you with three types of `renderer` callback functions: `headerRenderer`,
 * `renderer` and `footerRenderer`.
 *
 * Each of those renderer functions provides `root`, `column`, `model` arguments when applicable.
 * Generate DOM content, append it to the `root` element and control the state
 * of the host element by accessing `column`. Before generating new content,
 * users are able to check if there is already content in `root` for reusing it.
 *
 * Renderers are called on initialization of new column cells and each time the
 * related row model is updated. DOM generated during the renderer call can be reused
 * in the next renderer call and will be provided with the `root` argument.
 * On first call it will be empty.
 *
 * #### Example:
 * ```html
 * <vaadin-grid>
 *   <vaadin-grid-column></vaadin-grid-column>
 *   <vaadin-grid-column></vaadin-grid-column>
 *   <vaadin-grid-column></vaadin-grid-column>
 * </vaadin-grid>
 * ```
 * ```js
 * const grid = document.querySelector('vaadin-grid');
 * grid.items = [{'name': 'John', 'surname': 'Lennon', 'role': 'singer'},
 *               {'name': 'Ringo', 'surname': 'Starr', 'role': 'drums'}];
 *
 * const columns = grid.querySelectorAll('vaadin-grid-column');
 *
 * columns[0].headerRenderer = function(root) {
 *   root.textContent = 'Name';
 * };
 * columns[0].renderer = function(root, column, model) {
 *   root.textContent = model.item.name;
 * };
 *
 * columns[1].headerRenderer = function(root) {
 *   root.textContent = 'Surname';
 * };
 * columns[1].renderer = function(root, column, model) {
 *   root.textContent = model.item.surname;
 * };
 *
 * columns[2].headerRenderer = function(root) {
 *   root.textContent = 'Role';
 * };
 * columns[2].renderer = function(root, column, model) {
 *   root.textContent = model.item.role;
 * };
 * ```
 *
 * Alternatively, the content can be provided with Polymer's Templates:
 *
 * #### Example:
 * ```html
 * <vaadin-grid items='[{"name": "John", "surname": "Lennon", "role": "singer"},
 * {"name": "Ringo", "surname": "Starr", "role": "drums"}]'>
 *   <vaadin-grid-column>
 *     <template class="header">Name</template>
 *     <template>[[item.name]]</template>
 *   </vaadin-grid-column>
 *   <vaadin-grid-column>
 *     <template class="header">Surname</template>
 *     <template>[[item.surname]]</template>
 *   </vaadin-grid-column>
 *   <vaadin-grid-column>
 *     <template class="header">Role</template>
 *     <template>[[item.role]]</template>
 *   </vaadin-grid-column>
 * </vaadin-grid>
 * ```
 *
 * The following helper elements can be used for further customization:
 * - [`<vaadin-grid-column-group>`](#/elements/vaadin-grid-column-group)
 * - [`<vaadin-grid-filter>`](#/elements/vaadin-grid-filter)
 * - [`<vaadin-grid-sorter>`](#/elements/vaadin-grid-sorter)
 * - [`<vaadin-grid-selection-column>`](#/elements/vaadin-grid-selection-column)
 * - [`<vaadin-grid-tree-toggle>`](#/elements/vaadin-grid-tree-toggle)
 *
 * __Note that the helper elements must be explicitly imported.__
 * If you want to import everything at once you can use the `all-imports.html` bundle.
 *
 * A column template can be decorated with one the following class names to specify its purpose
 * - `header`: Marks a header template
 * - `footer`: Marks a footer template
 * - `row-details`: Marks a row details template
 *
 * The following built-in template variables can be bound to inside the column templates:
 * - `[[index]]`: Number representing the row index
 * - `[[item]]` and it's sub-properties: Data object (provided by a data provider / items array)
 * - `{{selected}}`: True if the item is selected (can be two-way bound)
 * - `{{detailsOpened}}`: True if the item has row details opened (can be two-way bound)
 * - `{{expanded}}`: True if the item has tree sublevel expanded (can be two-way bound)
 * - `[[level]]`: Number of the tree sublevel of the item, first level-items have 0
 *
 * ### Lazy Loading with Function Data Provider
 *
 * In addition to assigning an array to the items property, you can alternatively
 * provide the `<vaadin-grid>` data through the
 * [`dataProvider`](#/elements/vaadin-grid#property-dataProvider) function property.
 * The `<vaadin-grid>` calls this function lazily, only when it needs more data
 * to be displayed.
 *
 * See the [`dataProvider`](#/elements/vaadin-grid#property-dataProvider) in
 * the API reference below for the detailed data provider arguments description,
 * and the “Assigning Data” page in the demos.
 *
 * __Note that expanding the tree grid's item will trigger a call to the `dataProvider`.__
 *
 * __Also, note that when using function data providers, the total number of items
 * needs to be set manually. The total number of items can be returned
 * in the second argument of the data provider callback:__
 *
 * ```javascript
 * grid.dataProvider = function(params, callback) {
 *   var url = 'https://api.example/data' +
 *       '?page=' + params.page +        // the requested page index
 *       '&per_page=' + params.pageSize; // number of items on the page
 *   var xhr = new XMLHttpRequest();
 *   xhr.onload = function() {
 *     var response = JSON.parse(xhr.responseText);
 *     callback(
 *       response.employees, // requested page of items
 *       response.totalSize  // total number of items
 *     );
 *   };
 *   xhr.open('GET', url, true);
 *   xhr.send();
 * };
 * ```
 *
 * __Alternatively, you can use the `size` property to set the total number of items:__
 *
 * ```javascript
 * grid.size = 200; // The total number of items
 * grid.dataProvider = function(params, callback) {
 *   var url = 'https://api.example/data' +
 *       '?page=' + params.page +        // the requested page index
 *       '&per_page=' + params.pageSize; // number of items on the page
 *   var xhr = new XMLHttpRequest();
 *   xhr.onload = function() {
 *     var response = JSON.parse(xhr.responseText);
 *     callback(response.employees);
 *   };
 *   xhr.open('GET', url, true);
 *   xhr.send();
 * };
 * ```
 *
