docs: Obtains a variable value range.
  <p>
  This factory obtains a range where the minimum value is fixed and the maximum value may vary.
  For example, the ISO day-of-month always starts at 1, but ends between 28 and 31.
  
  @param min  the minimum value
  @param maxSmallest  the smallest maximum value
  @param maxLargest  the largest maximum value
  @return the ValueRange for min, smallest max, largest max, not null
  @throws IllegalArgumentException if
  the minimum is greater than the smallest maximum,
  or the smallest maximum is greater than the largest maximum
