 * @plugin HiddenColumns
 *
 * @description
 * Plugin allows to hide certain columns. The hiding is achieved by not rendering the columns. The plugin not modifies
 * the source data and do not participate in data transformation (the shape of data returned by `getData*` methods stays intact).
 *
 * Possible plugin settings:
 *  * `copyPasteEnabled` as `Boolean` (default `true`)
 *  * `columns` as `Array`
 *  * `indicators` as `Boolean` (default `false`).
 *
 * @example
 *
 * ```js
 * const container = document.getElementById('example');
 * const hot = new Handsontable(container, {
 *   data: getData(),
 *   hiddenColumns: {
 *     copyPasteEnabled: true,
 *     indicators: true,
 *     columns: [1, 2, 5]
 *   }
 * });
 *
 * // access to hiddenColumns plugin instance:
 * const hiddenColumnsPlugin = hot.getPlugin('hiddenColumns');
 *
 * // show single column
 * hiddenColumnsPlugin.showColumn(1);
 *
 * // show multiple columns
 * hiddenColumnsPlugin.showColumn(1, 2, 9);
 *
 * // or as an array
 * hiddenColumnsPlugin.showColumns([1, 2, 9]);
 *
 * // hide single column
 * hiddenColumnsPlugin.hideColumn(1);
 *
 * // hide multiple columns
 * hiddenColumnsPlugin.hideColumn(1, 2, 9);
 *
 * // or as an array
 * hiddenColumnsPlugin.hideColumns([1, 2, 9]);
 *
 * // rerender the table to see all changes
 * hot.render();
 * ```
