   =head1 INTRODUCTION
   
   This module publishes a directory of files.
   
   This is part of the LearningOnline Network with CAPA project
   described at http://www.lon-capa.org.
   
   =head1 HANDLER SUBROUTINE
   
   This routine is called by Apache and mod_perl.
   
   =over 4
   
   =item *
   
   read in information
   
   =item *
   
   start page output
   
   =item *
   
   run through list of files and attempt to publish unhidden files
   
   =back
   
   =head2 OTHER SUBROUTINES:
   
   =head3 startpage($r, $uame, $udom, $thisdisfn)
   
   Output the header of the page.  This includes:
    - The HTML header 
    - The H1/H3  stuff which includes the directory.
    
       startpage($r, $uame, $udom, $thisdisfn);
           $r     - The apache request object.
           $uname - User name.
           $udom  - Domain name the user is logged in under.
           $thisdisfn - Displayable version of the filename.
   
   =head3 getTitleString($fullname)
   
       Get the title string or "[untitled]" if the file has no title metadata:
       Without the latter substitution, it's impossible to examine metadata for
       untitled resources.  Resources may be legitimately untitled, to prevent
       searches from locating them.
       
       $str = getTitleString($fullname);
           $fullname - Fully qualified filename to check.
   
   =head3 putdirectory(r, base, here, dirname, modtime)
   
       Put out a directory table row:
       
       putdirectory($r, $base, $here, $dirname, $modtime)
           $r       - Apache request object.
           $reqfile - File in request.
           $here    - Where we are in directory tree.
           $dirname - Name of directory special file.
           $modtime - Encoded modification time.
   
   =head3 CategorizeFiles($location, $files)
       
       Categorize files in the directory.
       For each file in a list of files in a file directory, 
       the  file categorized as one of:
           - directory  
           - sequence
           - problem 
           - Other resource.
   
       For each file the modification date is determined as well.
       Returned is a list of sublists:
           (directories, sequences, problems, other)
       each of the sublists contains entries of the following form (sorted by filename):
       (filename, typecode, lastmodtime)
       
           $list = CategorizeFiles($location, $files)
           $location   - Directory in which the files live (relative to our execution)
           $files      - list of files.
