- Syllabus.
- code migrated from handler() to new subroutines to facilitate reuse.
- &save_changes() - used to process and store changes to syllabus made
by CC.
- &print_header() - used to call start_page etc., after any updates have
been stored by &save_changes
- &get_personnel() - used to build display of course personnel.
- Templated syllabus page
- checkboxes for fields can be used to hide fields which currently contain
entries (note these fields will still be viewable on pre-LON-CAPA 2.11
servers).
