  # In order to start listening to server events, this is all the code that we

  #
  #     ServerSentEvents.listen("http://example.com") do |event|
  #       puts event
  #     end
  #
  # @param address [String, URI] SSE endpoint
  # @param headers [Hash] HTTP headers to use when connecting
  # @param callback code block that should be executed on event arrival
  def self.listen(address, headers = {}, &callback)
    create_client(address, headers).listen(&callback)

  # Create new client that uses default parser to parse events.
  #
  # @param address [String, URI] SSE endpoint
  # @param headers [Hash] HTTP headers to use when connecting
  # @return [Client] client
