Find the proper method for setting a column visibility in

secures the "name" columns.

+3. Build and run.  What data do you see? 
+* You should see all of the data except the secret identities of Batman and 
Robin. This is because the `Scanner` was created from the root user which 
doesn't have the `secretId` authorization. 
+* Replace the `Authorizations.EMPTY` in the Scanner with the `auths` variable 
created above and run it again. 
+* This should result in an error since the root user doesn't have the 
authorizations we tried to pass to the Scanner.
