def add_gateway_routes
  # The routes required a Gateway Resource to contain them.
  # TODO: Support more routes. Right now outputing all routes in 1 template will hit the 60 routes limit.
  # Will have to either output them as a joined string or break this up to multiple templates.
  # http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cloudformation-limits.html
  # Outputs: Maximum number of outputs that you can declare in your AWS CloudFormation template. 60 outputs
  # Output name: Maximum size of an output name. 255 characters.
  #

  # build the parent ApiGateway::Resource nodes also
