=head1 Routines for version requirements for current course.

=over 4

=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.

=item * &needs_coursereinit()

Determine if course contents stored for user's session needs to be
refreshed, because content has changed since "Big Hash" last tied.

Check for change is made if time last checked is more than 10 minutes ago
(by default).

Inputs:

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

$interval (optional) - Time which may elapse (in s) between last check for content
change in current course. (default: 600 s).

Returns: an array; first element is:

=over 4

'switch' - if content updates mean user's session
needs to be switched to a server running a newer LON-CAPA version

'update' - if course session needs to be refreshed (i.e., Big Hash needs to be reloaded)
on current server hosting user's session

'' - if no action required.

=back

If first item element is 'switch':

second item is $switchwarning - Warning message if no suitable server found to host session.

third item is $switchserver - query string to append to /adm/switchserver containing lonHostID
and current role.

otherwise: no other elements returned.
