Functions
std::vector< std::uint64_t >	getVec (const IntVect &v, bool reverse)
	Convert an IntVect to a std::vector<std::uint64_t> (used for compatibility with openPMD-api)
std::vector< double >	getVec (const Real *v, bool reverse)
	Convert Real* pointer to a std::vector<double>, (used for compatibility with the openPMD API)
std::vector< std::uint64_t >	getReversedVec (const IntVect &v)
	Convert an IntVect to a std::vector<std::uint64_t> and reverse the order of the elements (used for compatibility with the openPMD API)
std::vector< double >	getReversedVec (const Real *v)
	Convert Real* pointer to a std::vector<double>, and reverse the order of the elements (used for compatibility with the openPMD API)
