- reordered includes to prevent accidental dependencies. - moved arch specific files into their own folder (easier to include with cmake). - renamed non-class files to reflect new code style (lower case with underscores). - using full relative paths for includes (easier for understanding dependencies). - using #pragma once instead of classic-style header guards.
