.year_ranges_major_digits(first:, last:, step:, major_first_digit:) ⇒ Object

generate year ranges, but prefer to start with the given major digit i.e. if the major first digit is 1 and step is 10, we could get the ranges 50-50,51-60,61-70,71-72 if the major first digit is 0 and step is 10, we could get the ranges 50-59,60-69,70-72
