/**
 * 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.
