44       * This method is called by the scheduler to send the reminder

47       * include as the first parameter the base url of the server including
48       * the scheme, hostname, port, and context. For example:
49       * <br>
50       * http://localhost:8080/itracker
51       * <br>
52       * If no other arguments are supplied it sends reminders to all
53       * owners/admins of unresolved issues in all projects that have not been
54       * modified in 30 days. The second element of the array can be a number
55       * that represents the number of days to use to check the last modified
56       * date. The third optional element is a number that represents the project
57       * id to limit the notifications to. A fourth optional argument is the severity
58       * to send the notification for.
59       * @param args optional arguments to configure the notification messages
