Integrate call to join the game

[smileydts]

Player 0 goes to the page, enters name, clicks join, gets back player_id which his browser stores as a cookie.

Use Javascript -- I don't think AJAX is necessary, but maybe it is.

I can't remember if I shared this Postman collection with you or not, but in case not I'm attaching it here. dog.postman_collection.json

To run:

1. docker-compose up
2. Go to postman.com
3. Sign up for free account (if not already signed up)
4. Open a workspace
5. Import the attached collection (click the import button)
6. Have fun running the API calls. The URL you can easily see -- the body can be seen by clicking on "body"

Things to do.

• Store the player_id as a cookie
• run get_players to get the list of all the players in the game (try doing this on clicking the join button for now)
• Incorporate the data from get_players into the webpage (i.e. see the players that are in the game seated at the table)
• Try having 1-3 additional players already in the game using postman, then another joins with the browser
• use polling (or something) to constantly see what the list of players in the game is, and update accordingly
• Try having additional players join the game using postman and see that the game updates

Note: you may also be able to use incognito mode as a substitute for postman in this case
