 * `<vaadin-board>` is a web component to create flexible responsive layouts
 * and build nice looking dashboards.
 *
 * A `<vaadin-board>` is built using `<vaadin-board-row>` elements containing your child elements.
 * Each board row consists of four columns, and can contain up to four elements. Using column spans
 * you can tune the layout to your liking.
 *
 * ```html
 * <vaadin-board>
 *   <vaadin-board-row>
 *     <div>This could be chart 1</div>
 *     <div>This could be chart 2</div>
 *     <div>This could be chart 3</div>
