// CAlarmServer encapsulates a database server for alarms.  Alarms can be 
// created by DAQ (or any other) software entities, which notify alarm
// displayers, which log the alarm with this server.  The server is implemented
// using the gdbm UNIX database to store alarm content.  There are two database
// files:
//    (1) .alarmdb contains all of the alarm information fields, such as 
//        the logging faclity, the alarm status, the alarm message and date.
//    (2) .alarmcount contains experiment ID and alarm count information to be
//        used in generating count numbers for alarm displayers.
