- Bugs 4373 and 6131: recursive parameters.
- User interface changes for table mode: columns for display/setting
recursive parameters (map-level) eliminated, although levels retained.
- Parameters set for Enclosing Map/Folder can be set to "Recursive" in
pop-up menu.
- If a parameter is currently recursive, the text: recursive is shown
below the current value (clickable link); also shown in "Parameter
in effect" table cell.

35: lonparmset - Handler to set parameters for assessments and course
36:
37: =head1 SYNOPSIS
38:
39: lonparmset provides an interface to setting course parameters.
40:
41: It contains all the code for the "Content and Problem Settings" UI, except
42: for the helpers parameter.helper and resettimes.helper, and lonhelper.pm,
43: and lonblockingmenu.pm.
