+ * This means a level "LOG_LEVEL_ERROR >= Level <= LOG_LEVEL_ERROR_MAX" e.g.
+ * "Level := LOG_LEVEL_ERROR+2" is considered an error level.
+ * This is nice for debugging if you have more or less important debug messages.
+ * For example you can assign LOG_LEVEL_DEBUG+10 for the more important ones and
+ * LOG_LEVEL_DEBUG+20 for less important ones and so on. By changing the log-level
