   =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.

   =pod
   
   =item get_group_settings
   
   Uses TokeParser to extract group information from the
   XML used to describe course groups.
   
   Input:
   Scalar containing XML  - as retrieved from &coursegroups().
   
   Output:
   Hash containing group information as key=values for (a), and
   hash of hashes for (b)
   
   Keys (in two categories):
   (a) groupname, creator, creation, modified, startdate,enddate.
   Corresponding values are name of the group, creator of the group
   (username:domain), UNIX time for date group was created, and
   settings were last modified, and default start and end access
   times for group members.
   
   (b) functions returned in hash of hashes.
   Outer hash key is functions.
   Inner hash keys are chat,discussion,email,files,homepage,roster.
   Corresponding values are either on or off, depending on
   whther this type of functionality is available for the group.
