Rafael Kitover e29032d48a Switch to nonstd::optional due to mac build issues ... Switch usage of std::optional to nonstd::optional for now because of an error from the Mac builder script, I cannot reproduce the problem yet but will try to fix it later, it may not be fixable when targeting 10.7. The header is from: https://github.com/martinmoene/optional-lite . Usage is about the same, to include: `#include "nonstd/optional.hpp"` Then use nonstd::optional and nonstd::nullopt instead of the std:: counterparts.
