// Macro to log an error and throw an exception.
// Inspired by ErrorMacros.hpp in opm-common.
// NOTE: For this macro to work, the
// exception class must exhibit a constructor with the signature
// (const std::string &message). Since this condition is not fulfilled
// for the std::exception, you should use this macro with some
// exception class derived from either std::logic_error or
// std::runtime_error.
