/**
 * A very simple panel showing alarms published in the source channel.
 * 
 * This panel shows the alarms published by sources in the notification channel.
 * These are the same alarms the alarm service listens to.
 * Alarms published in the source NC can be considered as RAW alarms because 
 * they do not contain any info for operators (that is added by the alarm service 
 * component and published in the category NCs).
 * This panel can be very useful for debugging purposes when the
 * intention of the developer is to check the generation of the alarms.
 * 
 * <EM>This GUI is not intended for operators because the information it provides
 * is not complete. <B>Operators shall use the alarmPanel instead.</B></EM>
