/**
 * @plugin ManualColumnMove
 * @class ManualColumnMove
 *
 * @description
 * This plugin allows to change columns order. To make columns order persistent the {@link Options#persistentState}
 * plugin should be enabled.
 *
 * API:
 * - `moveColumn` - move single column to the new position.
 * - `moveColumns` - move many columns (as an array of indexes) to the new position.
 * - `dragColumn` - drag single column to the new position.
 * - `dragColumns` - drag many columns (as an array of indexes) to the new position.
 *
 * [Documentation](@/guides/columns/column-moving.md) 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 columns.
 * - guideline - line which shows where columns has been moved.
 *
