Translate Python exception into C++ exception (Boost::Python)

BoostPythonTranslateException.h

/**
 * @brief   Generic Python-to-C++ exception translator
 *          Caller provides C++ exception class, callback(), list of Python exceptions,
 *          which should be be handled and optional parameters to callback
 *
 * @param   callback object, usually python function, lambda function, functor, std::bind expression or std::function
 * @param   exceptions list of python exceptions, e.g. { PyExc_ValueError, PyExc_TypeError }
 * @param   params optional parameters to callback()
 * @return  decltype - return value of the callback()
 *
 *          Example:
 *
 *          const auto exceptions = { PyExc_KeyError, PyExc_ValueError };
 *          const auto callback = []() { return py::dict()["key"]; }; // throws KeyError when called
 *
 *          try
 *          {
 *              auto result = translate<std::exception>( callback, exceptions );
 *          }
 *          catch( const std::exception& )
 *          {
 *              std::cout << "key error occured" << std::endl;
 *          }
 *
