This class, which employs the Dispatcher class, provides a frontend to
telegram.Bot to the programmer, so they can focus on coding the bot. It's
purpose is to receive the updates from Telegram and to deliver them to said
dispatcher. It also runs in a separate thread, so the user can interact
with the bot, for example on the command line. The dispatcher supports
handlers for different kinds of data: Updates from Telegram, basic text
commands and even arbitrary types.
The updater can be started as a polling service or, for production, use a
webhook to receive updates. This is achieved using the WebhookServer and
WebhookHandler classes.

token (Optional[str]): The bot's token given by the @BotFather
