  def create
    # The only things we need to handle in here (for now at least) are entries.
    # If there's been an update or a deletion, we just remove the cached timestamp.
    # The updated_at method which is included in ContentfulModel::Base in this gem
    # will check the cache first before making the call to the API.

    # We can then just use normal Rails russian doll caching without expensive API calls.
