/**
 * @plugin AutoColumnSize
 *
 * @description
 * This plugin allows to set column widths based on their widest cells.
 *
 * By default, the plugin is declared as `undefined`, which makes it enabled (same as if it was declared as `true`).
 * Enabling this plugin may decrease the overall table performance, as it needs to calculate the widths of all cells to
 * resize the columns accordingly.
 * If you experience problems with the performance, try turning this feature off and declaring the column widths manually.
 *
 * Column width calculations are divided into sync and async part. Each of this parts has their own advantages and
 * disadvantages. Synchronous calculations are faster but they block the browser UI, while the slower asynchronous
 * operations don't block the browser UI.
 *
 * To configure the sync/async distribution, you can pass an absolute value (number of columns) or a percentage value to a config object:
 * ```js
 * // as a number (300 columns in sync, rest async)
 * autoColumnSize: {syncLimit: 300},
 *
 * // as a string (percent)
 * autoColumnSize: {syncLimit: '40%'},
 * ```
 *
 * To configure this plugin see {@link Options#autoColumnSize}.
 *
 * @example
 * ```js
 * const hot = new Handsontable(document.getElementById('example'), {
 *   date: getData(),
 *   autoColumnSize: true
 * });
 * // Access to plugin instance:
 * const plugin = hot.getPlugin('autoColumnSize');
 *
 * plugin.getColumnWidth(4);
 *
 * if (plugin.isEnabled()) {
 *   // code...
 * }
 * ```
