WIP: Customer floor

Trying to implement the stream between customer choices and restaurants

End Goals: 

Allow a person to click the circle, which populates a check in button.
The person clicks the button and sends a post request with the id of the element they selected to the restaurant controller, creating an "example" object in the DB. 
The restaurant page updates with the objects in the database.

Points of interest: how do you get the streaming page to dynamically insert just the new items?
