=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.

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
whether this type of functionality is available for the group.
