@areas.group_by(&:responsibility).each do |responsibility, areas|
<%=h responsibility.name %><% areas.each do |area| %> ...
I see that #group_by iterates through my list of areas, splitting them
sets according to which ones have the same responsibility.
I would like to sort the results of that list.
It seems to me that group_by returns an OrderedHash. How to I sort
results prior to passing the |responsibility, areas| pairs?
