Replace old-style include guards with #pragma once

[Ahmad-Bamba]

In every .h file in the repo right now, there is a set of two lines in the beginning and one at the end which look like this:

#ifndef [file]
#define [file]
...
#endif

These need to all be replaced with a single #pragma once at the top of the file.

So I delete the

ifndef [file]

define [file]

...

endif

and type a #pragma one on the top?

right?

[Ahmad-Bamba]

pragma once, right. But leave the part in in-between the the #define and #endif (obviously 😄 )

Ok thanks
