+/**
+ * Element access to Web Storage API (window.localStorage).
+ *
+ * Keeps `value` property in sync with localStorage.
+ *
+ * Value is saved as json by default.
+ *
+ * ### Usage:
+ *
+ * `ls-sample` will automatically save changes to its value.
+ *
+ *     <dom-module id="ls-sample">
+ *       <iron-localstorage name="my-app-storage"
+ *         value="{{cartoon}}"
+ *         on-iron-localstorage-load-empty="initializeDefaultCartoon"
+ *       ></iron-localstorage>
+ *     </dom-module>
+ *
+ *     <script>
+ *       Polymer({
+ *         is: 'ls-sample',
+ *         properties: {
+ *           cartoon: {
+ *             type: Object
+ *           }
+ *         },
+ *         // initializes default if nothing has been stored
+ *         initializeDefaultCartoon: function() {
+ *           this.cartoon = {
+ *             name: "Mickey",
+ *             hasEars: true
+ *           }
+ *         },
+ *         // use path set api to propagate changes to localstorage
+ *         makeModifications: function() {
+ *           this.set('cartoon.name', "Minions");
+ *           this.set('cartoon.hasEars', false);
+ *         }
+ *       });
+ *     </script>
+ *
+ * ### Tech notes:
+ *
+ * * `value.*` is observed, and saved on modifications. You must use
+ *     path change notification methods such as `set()` to modify value
+ *     for changes to be observed.
+ *
+ * * Set `auto-save-disabled` to prevent automatic saving.
+ *
+ * * Value is saved as JSON by default.
+ *
+ * * To delete a key, set value to null
+ *
+ * Element listens to StorageAPI `storage` event, and will reload upon receiving it.
+ *
+ * **Warning**: do not bind value to sub-properties until Polymer
+ * [bug 1550](https://github.com/Polymer/polymer/issues/1550)
+ * is resolved. Local storage will be blown away.
+ * `<iron-localstorage value="{{foo.bar}}"` will cause **data loss**.
