-     * Store or retrieve settings.
-     *
-     * Settings are further subdivided into groups. For example: global,
-     * seminar- and user-specific settings (see below).
-     *
-     * HTTP GET
-     * returns a JSON object with current settings.
-     *
-     * HTTP PUT
-     * expects a JSON object with settings to store and returns
-     * updated settings as a JSON object. Some settings are read-only,
-     * others can only be set if the user has the necessary access level.
-     *
-     * Currently only the following basic features are supported:
-     *
-     * HTTP GET wysiwyg/settings/global
-     *   Always returns:
-     *   {
-     *     "upload": {
-     *       "permission": "autor",
-     *         "folder": {
-     *           "name": "Wysiwyg Uploads",
-     *           "description": "Vom WYSIWYG Editor hochgeladene Dateien."
-     *         }
-     *       }
-     *     }
-     *   }
-     *
-     * HTTP GET wysiwyg/settings/users/current
-     *   Always returns following setting for the authenticated user:
-     *   {
-     *     "disabled": false | true
-     *   }
-     *
-     * HTTP PUT wysiwyg/settings/users/current
-     *   Allows only to reset or set the disabled state with:
-     *   {
-     *     "disabled": false | true
-     *   }
-     *
-     * Below is a specification of possible future extensions to this
-     * interface, that are based on current feature requests by users
-     * (mainly people from ELMO, ELAN and ECULT).
-     *
-     * wysiwyg/settings/global
-     *   Common settings for all WYSIWYG editors throughout Stud.IP.
-     * wysiwyg/settings/seminars
-     *   Settings of all seminars.
-     *   Listed seminars depend on access level:
-     *     root => full access to all seminars
-     *     dozent, tutor of a seminar => full access to those seminars
-     *     others => read-access to seminars they are a member of
-     * wysiwyg/settings/seminars/ID
-     *   Settings of the seminar with the given ID.
-     *   Access permissions: see above.
-     * wysiwyg/settings/seminars/ID/users
-     *   Seminar's settings for all its users.
-     *   Access permissions: see above.
-     * wysiwyg/settings/seminars/ID/users/ID
-     *   Seminar's settings for a specific user in that seminar.
-     *   Access permissions: see above.
-     * wysiwyg/settings/users
-     *   Settings of all users.
-     *   Listed users depend on access level:
-     *     root => full access to all users
-     *     not root => full access to own settings only
-     * wysiwyg/settings/users/ID
-     *   Settings of the user with the given ID.
-     *   Access permissions: see above.
-     * wysiwyg/settings/users/ID/seminars
-     *   User's settings for all seminars the user is a member of.
-     *   Access permissions: see above.
-     * wysiwyg/settings/users/ID/seminars/ID
-     *   User's settings for the seminar with the given ID.
-     *   Access permissions: see above.
-     *
-     * The difference of seminar's settings for a user and user's settings
-     * for a seminar:
-     *
-     *   A seminar's teacher may want to set the upload directory for each user
-     *   to a separate one, which should not be overwritable by a user, in
-     *   order to make sure that users cannot see other users uploads (there
-     *   are other ways to do this, but it's just an example).
-     *
-     *   A user might want to have a specific upload directory in order to
-     *   collaborate better with other users in the same seminar (e.g. when
-     *   students form a study group).
-     *
-     *   For example the ELMO module needs such settings.
-     *
-     * JSON scheme for access to wysiwyg/settings:
-     * {
-     *   "global": { "SETTING": ..., ... },
-     *   "seminars": {
-     *     "ID": {
-     *       "users": { "ID": {...}, ... },
-     *       "SETTING": ...,
-     *       ...
-     *     },
-     *     "ID": {...},
-     *     ...
-     *   },
-     *   "users": {
-     *     "ID": {
-     *       "seminars": { "ID": {...}, ... },
-     *       "SETTING": ...,
-     *       ...
-     *     },
-     *     "ID": {...},
-     *     ...
-     *   }
-     * }
-     *
-     * When accessing a sub-resource that resource's branch of the JSON scheme
-     * will be returned.
