> Access Control: when processes try to read from the column groups, Zebra 
> should be able to handle allowed vs. disallowed user/application accesses. 
> Expected behavior when column group permissions are set:
>     When user selects only columns that they do not have permissions to 
> access, Zebra should return error with message "Error #: Permission denied 
> for accessing column <column name or names> 
> Access control applies to an entire column group, so all columns in a column 
> group have same permissions.
