docs: Retrieve the mean and median from a ROOT histogram.
  
      Note:
          These values are not so trivial to calculate without ROOT, as they are the bin values
          weighted by the bin content.
  
      Args:
          hist: Histogram from which the values will be extract.
      Returns:
          mean, median of the histogram.
