	Course domain and number will be taken from user's

	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.

	Input:

	Keys (in two categories):

	(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.

	Retrieves usernames:domains for users in the specified course

	Incoming parameters:
	1. course domain
	2. course number
	3. access status: users must have - either active,

	4. reference to array of permissible roles
	5. reference to array of section restrictions (optional)
	6. reference to results object (hash of hashes).
	7. reference to optional userdata hash
	Keys of top level hash are roles.
	Keys of inner hashes are username:domain, with
	values set to access type.
	Optional userdata hash returns an array with arguments in the
	same order as loncoursedata::get_classlist() for student data.

	Entries for end, start, section and status are blank because
