Summary: Moved c implementation of `YGNode` to C++ struct. Not moving to C++ class as the React Classes dependent on `Yoga.h` assume it to be C. Thats why keeping `Yoga.h` C compatible. Sorry for the long diff, didn't thought that it will turn out to be this much big.Will keep an eye on number of lines next time 😉
