 #  Utility function used when rendering the <student> tag.  
 #  This function renders a segment of course personel  
 #  Personel are broken up by the helper into past, current and  
 #  future...each one gets is own subpage of selection.  
 #  This sub renders one of these pages.  
 #  Parameters:  
 #     $sections    - Set of sections in the course (hash reference).  
 #     $students    - Students in the section. (ref to array of references  
 #                    to arrays).  
 #     $formprefix  - form path prefix for form element names  
 #                    This is used to make each form element  
 #                    so that the segments having to do with each  
 #                    set of students won't collide.  
 #     $defaultusers - reference to a hash containng  
 #                     the set of users that should be on or off.  
 #  Returns:  
 #     HTML  text to add to the rendering of the helper.
