+/**
+ * This component watches a navigation bar and is able to link it alternative links, and automatic switch
+ * on page load.
+ *
+ * You can add button with class tab-link when they are clicked the tab target is fetched
+ * from the button's data property targetTab (so data-target-tab), it then search for a tab
+ * which targets matches in the navbar and simulates a click on it.
+ *
+ * Alternatively it also checks on page load if a hash matches a tab and activates it if one is found,
+ * and of course the hash is kept in sync when the navbar or alternative links are used.
