HEAD
Re-enable groups links in ENRL page. Add interface to allow group creator to specify mapping of different roles/sections to a group to support auto-add and auto-drop changes in group membership based on role changes of course participants. Implement ability to modify group settings, and to add new members. Changes to loncommon.pm to accommodate extraction of mapping options (roles & sections) when parsing group record in coursegroups.db file. Still working on ability to change functions/privileges/status of existing members.
