/**
 * @plugin ManualRowMove
 *
 * @description
 * 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.
 * - `dragRow` - drag single row to the new position.
 * - `dragRows` - drag many rows (as an array of indexes) to the new position.
 *
 * [Documentation](/demo-moving.html#manualRowMove) explain differences between drag and move actions. Please keep in mind that 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.
 *
 * @class ManualRowMove
 * @plugin ManualRowMove
