  Module to fetch institutional class list data. Each LON-CAPA domain should create its own customized version.  This version is specific to MSU data sources maintained by the Registrar's office.
  Retrieves enrollment data from LONCAPA_ClassList view in RO_ClassList database.  Writes enrollment for a LON-CAPA course in XML to a file in /home/httpd/perl/tmp.  Data is retrieved and processed by routines in LONCAPA::Enrollment.
