/**
 * @description
 * This plugin enables the copy/paste functionality in the Handsontable. The functionality works for API, Context Menu,
 * using keyboard shortcuts and menu bar from the browser.
 * Possible values:
 * * `true` (to enable default options),
 * * `false` (to disable completely)
 *
 * or an object with values:
 * * `'columnsLimit'` (see {@link CopyPaste#columnsLimit})
 * * `'rowsLimit'` (see {@link CopyPaste#rowsLimit})
 * * `'pasteMode'` (see {@link CopyPaste#pasteMode})
 *
 * See [the copy/paste demo](https://docs.handsontable.com/demo-copy-paste.html) for examples.
 *
 * @example
 * ```js
 * // Enables the plugin with default values
 * copyPaste: true,
 * // Enables the plugin with custom values
 * copyPaste: {
 *   columnsLimit: 25,
 *   rowsLimit: 50,
 *   pasteMode: 'shift_down',
 * },
 * ```
