Session 8: Add unique user id to any visitor

Описание: In previous videos we setup a page to show a 3D scene and then added the ability to press cursor keys to move the camera in the scene. We then broadcast these messages to all connected browsers. However we were unable to identify who was moving where because the messages did not contain a user id.

In this video, we a random member_id to the session for anyone visiting the site. Then pass this member_id to the frontend via the controller and template. Then include the member_id in any websocket communications so that we know who is doing the moving
