Course Requests
- Move &build_batchcreatehash() from lonrequestcourse.pm to loncoursequeueadmin.pm
- Move call to LONCAPA::batchcreatecourse into a separate routine: &course_creation()
within loncoursequeueadmin.pm
- Code added for resolution of course requests subject to approval by DC.
- either approve and create course, or reject.
- formatting of LON-CAPA messages sent to notification list and requestor improved.
- Change in storage of status information for a request.
- Status now stored in a separate key => value in courserequests.db file belonging to requestor
- key is status:$cdom:$cnum
- User's display of pending requests now shows the required information.
(Select button to view/modify/cancel individual request currently inactive - work in progress).
