I agree we need debug mode documentation. Contributions welcome.

The intent is include this source in both debug and release builds, and that it only be a minor size penalty in the dylib, with no run time hit when debug mode is not activated. The intent is also that activating debug mode does not change the ABI. However this intent is not well tested at this point.
