Three archeological ages (see Wikipedia)
    The three-age system is the periodization of human prehistory into three consecutive time periods, named for their respective predominant tool-making
    technologies. I summarize for my own use the most relevant attributes. The dates are indicative, they can vary thousands of years depending on region and authors. I have only included cultures
    that are of interest to me.
