 =item &enumerate_course_contents()  
   
 Create hashes of maps (for folders/pages) and symbs (for resources) in  
 a course, where keys are numbers (starting with 1) and values are  
 map url, or symb, for an iteration through the course, as seen by  
 a Course Coordinator. Used to generate numerical IDs to facilitate  
 storage of lists of maps or resources to be blocked during an exam.     
   
 Inputs: 3  
       $navmap - navmaps object  
   
       $map_url - reference to hash to contain URLs of maps in course  
   
       $resource_symb - reference to hash to contain symbs for  
                        resources in course  
   
 Outputs: None  
   
 Side Effects: $map_url and $resource_symb hashrefs are populated.

 =item &path_to_trigger()  
   
 Provides hierarchy of names of folders/sub-folders containing the current  
 item identified as an item with an interval timer set, to be used as a   
 trigger.   
   
 Inputs: 3   
      - $navmap - navmaps object  
   
      - $map - url for map (either the trigger itself, or map containing  
                            the resource, which is the trigger).   
   
      - $type - type of trigger: map or resource.  
   
 Outputs: 1 @pathitems - array of folder/subfolder names.
