def get_percentages total_word_count
  @word_counters.each_with_object({}) do |wc, hash|
    hash[wc.name] = round( 100 * (wc.count.to_f / total_word_count))
  end
end

#get_ratios ⇒ Object

We get the ratios of counts among all word_lists This returns a hash with keys that are named “name_to_other_name” This loop does twice as much work as it needs to, since the ratios

are reciprocals of one another, but oh well! It's only division.
