options is an object that you may write your own properties to. The following properties are read by YouTubeNotifier:

• secret - A private key used by Pubsubhubbub, it is not required to include this property but it is highly recommended that you do. Defaults to undefined
• hubCallback - Your ip/domain name that will be used as a callback URL by Pubsubhubbub. It must be in a URL format, ex: 'https://example.com/'. This is a required property as the default is undefined.
• middleware - If you are going to use the notifier with a middle ware. Defaults to false.
• path - The path on which the server will interact with the hub. Defaults to '/'. Not required if you are using the notifier with a middleware.
• port - The port Pubsubhubbub will listen on. This must be an open port on your system. Defaults to port 3000. Not required if you are using the notifier with a middleware.
• hubUrl - The URL in which we listen to updates from. This shouldn't be changed unless you know what you're doing.
