 * @plugin Comments
 * @class Comments
 *
 * @description
 * This plugin allows setting and managing cell comments by either an option in the context menu or with the use of
 * the API.
 *
 * To enable the plugin, you'll need to set the comments property of the config object to `true`:
 * ```js
 * comments: true
 * ```
 *
 * or an object with extra predefined plugin config:
 *
 * ```js
 * comments: {
 *   displayDelay: 1000,
 *   readOnly: true,
 *   style: {
 *     width: 300,
 *     height: 100
 *   }
 * }
 * ```
 *
 * To add comments at the table initialization, define the `comment` property in the `cell` config array as in an example below.
 *
 * @example
 * ::: only-for javascript
 * ```js
 * const hot = new Handsontable(document.getElementById('example'), {
 *   data: getData(),
 *   comments: true,
 *   cell: [
 *     {row: 1, col: 1, comment: {value: 'Foo'}},
 *     {row: 2, col: 2, comment: {value: 'Bar'}}
 *   ]
 * });
 *
 * // Access to the Comments plugin instance:
 * const commentsPlugin = hot.getPlugin('comments');
 *
 * // Manage comments programmatically:
 * commentsPlugin.setCommentAtCell(1, 6, 'Comment contents');
 * commentsPlugin.showAtCell(1, 6);
 * commentsPlugin.removeCommentAtCell(1, 6);
 *
 * // You can also set range once and use proper methods:
 * commentsPlugin.setRange({from: {row: 1, col: 6}});
 * commentsPlugin.setComment('Comment contents');
 * commentsPlugin.show();
 * commentsPlugin.removeComment();
 * ```
 * :::
 *
 * ::: only-for react
 * ```jsx
 * const hotRef = useRef(null);
 *
 * ...
 *
 * <HotTable
 *   ref={hotRef}
 *   data={getData()}
 *   comments={true}
 *   cell={[
 *     {row: 1, col: 1, comment: {value: 'Foo'}},
 *     {row: 2, col: 2, comment: {value: 'Bar'}}
 *   ]}
 * />
 *
 * // Access to the Comments plugin instance:
 * const hot = hotRef.current.hotInstance;
 * const commentsPlugin = hot.getPlugin('comments');
 *
 * // Manage comments programmatically:
 * commentsPlugin.setCommentAtCell(1, 6, 'Comment contents');
 * commentsPlugin.showAtCell(1, 6);
 * commentsPlugin.removeCommentAtCell(1, 6);
 *
 * // You can also set range once and use proper methods:
 * commentsPlugin.setRange({from: {row: 1, col: 6}});
 * commentsPlugin.setComment('Comment contents');
 * commentsPlugin.show();
 * commentsPlugin.removeComment();
 * ```
