* SnipePermissionsPolicy provides methods for handling the granular permissions used throughout Snipe-IT.
* Each "area" of a permission (which is usually a model, like Assets, Departments, etc), has a setting
* in config/permissions.php like view/create/edit/delete (and sometimes some extra stuff like
* checkout/checkin, etc.)
*
* A Policy should exist for each of these models, however if they only use the standard view/create/edit/delete,
* the policy can be pretty simple, for example with just one method setting the column name:
*
* protected function columnName()
* {
* return 'manufacturers';
* }
