=item parmval
Figure out a cascading parameter.
Inputs: $what - a parameter spec (incluse part info and name I.E. 0.weight)
$id - a bighash Id number
$def - the resource's default value 'stupid emacs
Returns: A list, the first item is the index into the remaining list of items of parm valuse that is the active one, the list consists of parm values at the 14 possible levels
14 - General Course
13 - Map or Folder level in course
12- resource default
11- map default
10 - resource level in course
9 - General for section
8 - Map or Folder level for section
7 - resource level in section
6 - General for group
5 - Map or Folder level for group
4 - resource level in group
3 - General for specific student
2 - Map or Folder level for specific student
1 - resource level for specific student

=item check_cloners
Checks if new users included in list of allowed cloners
are valid users. Replaces supplied list with
cleaned list containing only users with valid usernames
and domains.
Inputs: $clonelist, $oldcloner
where $clonelist is ref to array of requested cloners,
and $oldcloner is ref to array of currently allowed
cloners.
Returns: string - comma separated list of requested
cloners (username:domain) who do not exist in system.
=item change_clone
Modifies the list of courses a user can clone (stored
in the user's environment.db file), called when a
change is made to the list of users allowed to clone
a course.
Inputs: $action,$cloner
where $action is add or drop, and $cloner is identity of
user for whom cloning ability is to be changed in course.
