  /**
   * Default / standard implementation for wait-/ready-indication:
   *
   * media-modules may signal that they are <code>preparing</code> a resource, and then that
   * they are <code>ready</code> via the {@link mmir.MediaManager#_preparing} and
   * {@link mmir.MediaManager#_ready}.
   *
   * This implementation provides a simple mechanism for showing these states to the user:
   * upon <em>preparing</em> an overlay with a "please wait" message is shown, and upon
   * <em>ready</em> the overlay is hidden again.
   *
   * See {@link #setWaitCaption} for details on setting a custom text message.
   *
   * In order to load this implementation, add the entry <code>"waitReadyIndicator"</code>
   * to the <code>mediaManager.plugins</code> list in the MMIR configuration file
   * at <code>config/configuration.json</code>:
   * <pre>
   * ...
   *   "mediaManager": {
   *    "plugins": {
   *      "browser": ["waitReadyIndicator",
   *                  // OR: {"mod": "waitReadyIndicator", "config": "url to css styles"},
   *                  "webAudio",
   *                  ...
   *      ],
   *      "cordova": ["waitReadyIndicator",
   *                  // OR: {"mod": "waitReadyIndicator", "config": "url to css styles"},
   *                  "androidAudioInput",
   *                  ...
   *      ]
   *      ...
   *    }
   *  },
   *  ...
   * </pre>
   * NOTE: the optional configuration value specifies an URL to a CSS file for styling the
   *       wait-/ready-indication dialog.
   *       If not specified, the default styling of stlne-wait-dlg is used.
   *
   * @example
   *
   * //starting to prepare a resource:
   * mmir.MediaManager._preparing();
   *
   * // do something ...
   *
   * //... when the resouce has been prepared
   * // and is ready to be used:
   * mmir.MediaManager._ready();
   *
