   The students_groups_table has 2 columns.  The first is the 'student_id', and the 
   second is the 'group_id'. These two columns comprise the PRIMARY KEY for this 
   table, as an individual student may be affiliated with more than one group at
   any time. This table is indexed on both student_id and group_id.
