    #     controlled so we don't need "offl" or "truth" in front of 
    #     the flags to distinguish what type of tool they are meant
    #     for, ie we will want a flags.referenceTracks and testTracks
    #     flags for the track collection names,
    #     and then RefSelector, TestSelector etc to specify
    #     which types of selector we want, and we will want
    #     RefSelector.minPT, TestSelector.minPT etc ( or
    #     maybe, even Reference.minPT without the "Selector")
    #     so the selectors can run on test, or refrence, without 
    #     leaking their ultimate use into the names of their flags
