+/**
+ * A class that encapsulates the data abstraction that we expect the TabNav to
+ * be passed as `@items`.
+ *
+ * You can use this class when you want to create tab-nav from javascript.
+ *
+ * Instead of doing this in the template layer:
+ *
+ * ```handlebars
+ * <TabNav @items={{array
+ *   (hash
+ *     label="First Tab"
+ *     href=(href-to "some.route")
+ *     selected=(is-href "some.route")
+ *   )
+ *   (hash
+ *     label="Second Tab"
+ *     href=(href-to "some.route")
+ *     selected=(is-href "some.route")
+ *   )
+ * }}
+ * ```
+ *
+ * You can do the following in a js-file:
+ *
+ * ```javascript
+ * export default class WootComponent extends Component {
+ *   // ...
+ *   get tabs() {
+ *    const { router } = this;
+ *    const owner = getOwner(this);
+ *     return [
+ *       new Tab({
+ *         label: 'First Tab',
+ *         route: 'some.route',
+ *         currentRouteName: router.currentRouteName,
+ *         owner
+ *        }),
+ *       // ...
+ *     ];
+ *   }
+ * }
+ * ```
