 * This plugin allows to change rows order. To make rows order persistent the {@link Options#persistentState}
 * plugin should be enabled.
 *
 * API:
 * - moveRow - move single row to the new position.
 * - moveRows - move many rows (as an array of indexes) to the new position.
 *
 * If you want apply visual changes, you have to call manually the render() method on the instance of handsontable.
 *
 * The plugin creates additional components to make moving possibly using user interface:
 * - backlight - highlight of selected rows.
 * - guideline - line which shows where rows has been moved.
