389

include guards have been removed and replaced with #pragma once

There are a few header files that did not have include guards or #pragma once, those i noted with a comment stating NO INCLUDE GUARDS

Yeah the headers without include guards you were noticing are there bc historically the codebase had a very crude way of using header files.. good thing you already placed comments, so we can just find&replace in files-them.

So two changes then we can merge:

• [x] squash the commits to one
  • called maybe [REFACTOR] replace include guards \n\n resolves #389
• [x] replace "//NO INCLUDE GUARDS" with "#pragma once"

If you want I can do the first when merging Thank you for your contribution Bryan!
