  ####### HOOKS #############################
  #
  # This hook gets called before the params
  # are being verified. It's a good place to add a content type
  # handler for instance like shown below.
  # If you don't need this hook, just delete it.
  # Note that you have access to the request context, see sinatra_ext.rb
  # in the wd_sinatra repository to see how this is implemented.
  #
  # @param [Hash] params the incoming params.
  # processed.
  # @returns [Hash] the pre processed params.
  def params_preprocessor_hook(params)
    if JSON_BODY_VERBS.include?(request.request_method)
      BodyParser.parse(params, request.body, request.content_type)
    else
      params
    end
  end

  # This hook gets called after the params are being verified.
  # You can use this hook to modify the params before sending them to
  # your service.
  #
  # @param [Hash] params the incoming params.
  # processed.
  # @returns [Hash] the post processed params.
  # def params_postprocessor_hook(params)
  # end

  # This hook gets called before dispatching any
  # requests.
  # 
  # Implementation example
