When BELTS is used by a school, it is used for preparing and
            presenting lessons to students. The following user roles will be
            required: 
- System administrator 
- Content manager 
- School administrator 
- Teacher 
 Setting up students in a school BELTS is optional.
            The requirement to create students is determined by how students
            will use BELTS to access lessons; if students will use lesson logins
            to access BELTS' lessons, then students do not need to be
            created.
