- the interview.view had different foreach loops for the visualization of the interview. I copy and pasted then checked all the opened and closed loops and conditions.
@todo: simplify this view to get a better way to personalize

- route fixed
- mapped new size for pdf export
@todo
- test pdf export with different screen size

I just moved
				<?php
				$emptyopen = true;
				?>
before the loop of the answers
elementary watson!

- i solved the issue with answer by converting the answer text column always in an array and then managing that as an array everywhere
- solved permission page by using a custom function isItemInArray checking for the couple [permission_id,study_id] to then check the checkbox
- the create study permission was not given because of a weird error by Laravel, it was searching for a app\study model while I was using a {user} bind

@todo
- solve bug in interview view page (onechoice+open)
- encrypt screenshots
- create manage users permission
- remove supervisors from user list ? so who can manage users can't change permissions or just leave user manage to supervisors?

- I can't interview anymore, I got to revert changes
