/**
 * @fileOverview
 *
 * Demo file to  illustrate  adjusting   the  SWISH  interface,  notably
 * modifying   the   navbar   menu.   This    code   is   loaded   using
 * swish_config:web_plugin/1           as           defined           in
 * config_available/plugin_menu.pl. It defines a  JavaScript module that
 * is executed by require.js after the  dependencies are loaded. We want
 * to post-configure the SWISH menu and thus  need to run after SWISH is
 * initialized. This is done using the trigger `post-config`.
 *
 * The navbar is edited using the  jQuery plugin `navbar`, notably using
 * `clearDropdown` which removes a complete  menu   or  a specific entry
 * from a menu and `populateDropdown` which adds  items to a pulldown of
 * the navigation bar. The added object is a function that may have some
 * properties that defines how exactly it is added. Notably:
 *
 *   - `glyph` is the name of a Bootstrap-3 glyph icon
 *   - `after` or `before` indicates the label of another item which
 *     is used to define the new location in the pulldown.
 *
 * Finally, we extend  the  `storage`  plugin.   This  is  normally  not
 * possible. The plugin is represented using a function `$.fn.<plugin>`,
 * but the methods are not exposed. We  have added a methods property to
 * the function of some of the plugins to allow modifying the methods.
 *
 * @version 0.2.0
