 This function cascades through the possible levels searching for a value for
 a parameter.  The levels are checked in the following order:
-user, course (at section level and course level), map, and lonnet::metadata.
+user, course (at group, section level and course level), map, and 
+lonnet::metadata.
 This function uses %parmhash, which must be tied prior to calling it.
 This function also requires %courseopt and %useropt to be initialized for
 this user and course.
