+#### options.timeout
+As requested in the Gnip docs (http://support.gnip.com/apis/powertrack/api_reference.html), this option in the constructor allows us to set a read timeout in the client. The recommended a value is >=30 seconds, so the constructor will throw an error if a smaller timeout is provided. The default value for this option is 35 seconds.
