 * LOG_LEVEL_[TYPE] defines the "minimum" index for logs of type TYPE. Each

 * 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
 * you can hide the less important ones.
