Example

$ iquery --auth-file <scidbadmin_login_authentication_file> -a
AFL% create_user('John', 'john_password');      -- You can't log in as this user, since 'john_password' is not a valid hash.
AFL% create_role('Engineering');                -- Create a new role called Engineering
AFL% create_role('Sales');                      -- Create a new role called Sales
AFL% add_user_to_role('John', 'Engineering', 'Sales');    -- Add John to both Engineering and Sales transactionally
AFL% show_roles_for_user('John');               -- Show John's roles.  A user always belongs to a role with the same name as the user.
