36 * \brief Provides C++14-compatible implementation of std::optional.
38 * This imports the implementation found in src/external from
39 * https://github.com/martinmoene/optional-lite.git.
41 * There is no Doxygen for this code, but it is intended to conform to
42 * that of std::optional, so look in the usual C++17 documentation for
43 * std::optional for that.
45 * \todo Remove when requiring C++17, which has a standardized version
46 * of std::optional.
