domcloner - Optional "domcloner" flag; has value=1 if user has ccc priv in domain being filtered by,
(used when DC is using course creation form)

codetitles - reference to array of titles of components in institutional codes (official courses).


Returns: %courses - hash of courses satisfying search criteria, keys = course IDs, values are corresponding colon-separated escaped description, institutional code, owner and type.

=item * &check_release_required()

Compares required LON-CAPA version with version on server, and
if required version is newer looks for a server with the required version.

Looks first at servers in user's owen domain; if none suitable, looks at
servers in course's domain are permitted to host sessions for user's domain.

Inputs:

$loncaparev - Version on current server (format: Major.Minor.Subrelease-datestamp)

$courseid - Course ID of current course

$rolecode - User's current role in course (for switchserver query string).

$required - LON-CAPA version needed by course (format: Major.Minor).


Returns:

$switchserver - query string tp append to /adm/switchserver call (if
current server's LON-CAPA version is too old.

$warning - Message is displayed if no suitable server could be found.

Inputs:

change in current course. (default: 600 s).

Returns: an array; first element is:
