/**
 * @alias Options
 * @constructor
 * @description

 * ## Constructor options
 *
 * Constructor options are applied using an object literal passed as a second argument to the Handsontable constructor.
 *
 * ```js
 * const container = document.getElementById('example');
 * const hot = new Handsontable(container, {
 *   data: myArray,
 *   width: 400,
 *   height: 300
 * });
 * ```
 *
 * ---
 * ## Cascading configuration
 *
 * Handsontable is using *Cascading Configuration*, which is a fast way to provide configuration options
 * for the entire table, including its columns and particular cells.
 *
 * Consider the following example:
 * ```js
 * const container = document.getElementById('example');
 * const hot = new Handsontable(container, {
 *   readOnly: true,
 *   columns: [
 *     {readOnly: false},
 *     {},
 *     {}
 *   ],
 *   cells: function(row, col, prop) {
 *     var cellProperties = {};
 *
 *     if (row === 0 && col === 0) {
 *       cellProperties.readOnly = true;
 *     }
 *
 *     return cellProperties;
 *   }
 * });
 * ```
 *
 * The above notation will result in all TDs being *read only*, except for first column TDs which will be *editable*, except for the TD in top left corner which will still be *read only*.
 *
 * ### The Cascading Configuration model
 *
 * ##### 1. Constructor
 *
 * Configuration options that are provided using first-level `handsontable(container, {option: "value"})` and `updateSettings` method.
 *
 * ##### 2. Columns
 *
 * Configuration options that are provided using second-level object `handsontable(container, {columns: {option: "value"}]})`
 *
 * ##### 3. Cells
 *
 * Configuration options that are provided using third-level function `handsontable(container, {cells: function: (row, col, prop){ }})`
 *
 * ---
 * ## Architecture performance
 *
 * The Cascading Configuration model is based on prototypical inheritance. It is much faster and memory efficient
 * compared to the previous model that used jQuery extend. See: [http://jsperf.com/extending-settings](http://jsperf.com/extending-settings).
 *
 * ---
 * __Important notice:__ In order for the data separation to work properly, make sure that each instance of Handsontable has a unique `id`.

   * @description
   * Turns on saving the state of column sorting, column positions and column sizes in local storage.
   *
   * You can save any sort of data in local storage to preserve table state between page reloads.  In order to enable
   * data storage mechanism, `persistentState` option must be set to `true` (you can set it either during Handsontable
   * initialization or using the `updateSettings` method). When `persistentState` is enabled it exposes 3 hooks:
   *
   * __persistentStateSave__ (key: String, value: Mixed)
   *
   *   * Saves value under given key in browser local storage.
   *
   * __persistentStateLoad__ (key: String, valuePlaceholder: Object)
   *
   *   * Loads `value`, saved under given key, form browser local storage. The loaded `value` will be saved in
   *   `valuePlaceholder.value` (this is due to specific behaviour of `Hooks.run()` method). If no value have
   *   been saved under key `valuePlaceholder.value` will be `undefined`.
   *
   * __persistentStateReset__ (key: String)
   *
   *   * Clears the value saved under `key`. If no `key` is given, all values associated with table will be cleared.
   *
   * __Note:__ The main reason behind using `persistentState` hooks rather than regular LocalStorage API is that it
   * ensures separation of data stored by multiple Handsontable instances. In other words, if you have two (or more)
   * instances of Handsontable on one page, data saved by one instance won't be accessible by the second instance.
   * Those two instances can store data under the same key and no data would be overwritten.
   *
   * __Important:__ In order for the data separation to work properly, make sure that each instance of Handsontable has a unique `id`.
