   #
   # connects to the institutional classlist data source,
   # reads classlist data and stores in an XML file
   # in /home/httpd/perl/tmp/
   #
   # classlist files are named as follows:
   #
   # DOMAIN_COURSE_INSTITUTIONALCODE_classlist.xml
   #
   # e.g., msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
   # where DOMAIN = msu  COURSE = 43551dedcd43febmsul1 
   # INSTITUTIONALCODE = fs03nop590001 
   # (MSU's course naming scheme - fs03 = Fall semester 2003, nop =
   # department name, 590 = course number, 001 = section number.)
   #
   # fetch_enrollment requires three arguments -
   # $dom - DOMAIN e.g., msu
   # $affiliatesref - a reference to a hash of arrays that contains LON-CAPA 
   # courses that are to be updated as keys, and institutional coursecodes 
   # contributing enrollment to that LON-CAPA course as elements in each array.
   # $replyref - a reference to a hash that contains LON-CAPA courses
   # that are to be updated as keys, and the total enrollment count in all 
   # affiliated sections, as determined from institutional data as hash elements. 
   #
   # As an example, if fetch_enrollment is called to retrieve institutional
   # classlists for a single LON-CAPA course - 43551dedcd43febmsul1 which 
   # corresponds to fs03nop590, sections 001, 601 and 602 , and the course
   # also accommodates enrollment from a crosslisted course in the ost
   # department - fs03ost580002:
   #
   # the affiliatesref would be a reference to %affiliates which would be:
   #
   # @{$affiliates{'43551dedcd43febmsul1'}} =
   #   ("fs03nop590001","fs03nop590601","fs03nop590602","fs03ost580002");
   #
   # fetch_enrollment would create four files in /home/httpd/perl/tmp/.
   # msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
   # msu_43551dedcd43febmsul1_fs03nop590601_classlist.xml

   #
   # The <startdate> and the <enddate> are the activation date and expiration date
   # for this student's role. If they are absent, then the default access start and
   # default access end dates are used. The default access dates can be set when 
   # the course is created, and can be modified using the Automated Enrollment
   # Manager, or via the 'Upload a class list','Enroll a single student' or 
   # 'Modify student data' utilities in the Enrollment Manager, by checking the 
   # 'make these dates the default for future enrollment' checkbox. If no default 
   # dates have been set, then the tudent role will be active immediately, and will 
   # remain active until the role is explicitly expired using ENRL -> Drop students. 
   # If dates are to included in the XML file, they should be in the format
   # YYYY:MM:DD:HH:MM:SS (: separators required).
   #
   # If there were 10 students in fs03nop590001, 5 students in fs03nop59o601, 
   # 8 students in fs03nop590602, and 2 students in fs03ost580002,
   # then $$reply{'43551dedcd43febmsul1'} = 25
   #
   # The purpose of the %reply hash is to detect cases where the institutional 
   # enrollment is 0 (most likely due to a problem with the data source).
   # In such a case, the LON-CAPA course roster is left unchanged (i.e., no
   # students are expired, even if automated drops is enabled.
   # 
   # fetch_enrollment should return a 0 or 1, depending on whether a connection
   # could be established to the institutional data source.
   # 0 is returned if no connection could be made.
   # 1 is returned if connection was successful
   #
   # A return of 1 is required for the calling modules to perform LON-CAPA
   # roster changes based on the contents of the XML classlist file(s), e,g,,
   # msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
   #
   # XML classlist files are temporary. They are deleted after the enrollment 
   # update process in the calling module is complete.
