using Codeigniter (and Grocery Crud) in phpStorm

There is an examples.php under controllers. If I try to run it, I get No Direct Script Access Allowed. From what I understand, I need to go through the index.php. I thought that was a CI requirement? Perhaps this problem is a grocery Crud "thing"? Honestly I am back to development after being away for 10 years and am amazed how little use of a debugger goes on these days. I can't imagaine writing anything of complexity without a debugger (I was a developer for 20 years)!

Talking about CI, is there a premade login script available in CI to use? Without a debugger I don't think I could write one from scratch. 

Thanks for your help, btw.
