standardize include format and pragma once All #ifndef guards on headers have been removed, I think, in favor of #pragma once Headers are now included as `#include "filename"` if the included file resides in the same directory as the file including it, or any subdirectory therein. Otherwise they are included as `#include <project/top/dir/relative/path/filename>` The above does not include system/os headers. 2021-03-09 22:24:35 +00:00			`#include <llarp/crypto/types.hpp>`
