   =item coursegroups
   
   Retrieve information about groups in a course,
   
   Input:
   1. Reference to hash to populate with group information. 
   2. Optional course domain
   3. Optional course number
   4. Optional group name
   
   Course domain and number will be taken from user's
   environment if not supplied. Optional group name will'
   be passed to lonnet::get_coursegroups() as a regexp to
   use in the call to the dump function.
   
   Output
   Returns number of groups in the course (subject to the
   optional group name filter).
   
   Side effects:
   Populates the referenced curr_groups hash, with key,
   value pairs. Keys are group names, corresponding values
   are scalars containing group information in XML. This
   can be sent to &get_group_settings() to be parsed.
