// VTL 2.1 10/07/2024 SDMX
// Custom:
// - Remove component duplication
// - Add distance operators (levenshtein)
// - rename year and month functions to getYear and getMonth
// Since 2.0:
// - add RANDOM operator
// - add CASE operator
// - add time operators: dateDiffAtom, dateAddAtom, yearAtom, monthAtom, dayOfMonthAtom, dayOfYearAtom, dayToYearAtom, dayToMonthAtom, yearTodayAtom, monthTodayAtom
