+ * icc-data.
+ *
+ * Some purposes may be:
+ * - aggregating of login data
+ * - managing of whoami, if additional data is needed, that the auth service
+ *   doesn't provide
+ * - To get history points
+ * - To get history data
+ * - To get the installed version
+ * - To query statistics
+ * - To calculate recursive trees (e.g. origins of motions; not possible with
+ *   the autoupdate service)
+ * - to synchronize the servertime for countdowns
+ *
+ * @throws PresenterException This exception might be thrown, if there was an
+ * server error (Http-500-equivalent). For user error (e.g. wrong data) use the
