   #  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.
