| | | | | * Some spaces look a little more verbose now, but that shouln't be a problem as it also should raise readability, too. * This makes some use of return-value-optimizations also.

| | | | | | | | | | | This change is made to (easily) be forward compatible with future C++ standards, in order to allow compiling the code with newer standards at some point in the future. * Removed the `using byte = uint8_t;` line from Common.h * Mechanically change all uses of `byte` to `uint8_t`.
