CVS tags:
HEAD
- Bug 5822.
- logging of changes to student-schedulable slots in nohist_$cdom_$cnum_slotlog.db file in a student's directory in lonUsers.
- users can view their own reservation history via "Reservations History link on "Manage Reservations" page.
- CCs/instructors can view history of reservation changes for a particular slot from "History" link in slots table
- CCs/instructors can view reservation changes for a particular student.
- use standard data tabling display
- users without vgr privilege can view reservation status for all resources in a course which use slots
- loncommon::sorted_slots() used to sort slots by start time.
- Breadcrumbs added
- Missing &mt()
*** Work in progress ... future amalgamation of code used for log display expected. ***
