{Test 14: Open and read from Employee Database with ISQLMonitor}

{  This is a simple use of IBX to access the employee database in console mode.
  The program opens the database, runs a query and writes the result to stdout.

  ISQLMonitor is used to trace the activity.

  The Monitor is in a separate process
