Add an update! method on HAL link collection

[chussenot]

If i use representer with HAL links, i've got error because update! method is not set on LinkColection class

      def represent_collection(collection, *args)
        representer, dummy, options = parse_arguments({}, *args)
        decorator = representer.new(dummy)
        collection.map do |item|
          decorator.update!(item)
          decorator.to_hash(options)
        end
      end

So how to implement this ?

class Roar::Hypermedia::LinkCollection
  def update!(arr)
    # ... Implement here
  end
end

When exactly does that happen? Can you paste the code that uses Roar and the representer, pleeeeease?
