/**
* The purpose of this file is to subscribe to the switch events and then notify the web socket service of the event.
*
* Requirements:
* - PHP 7.1 or higher
*
* When an event is received from the switch, it is sent to the web socket service. The web socket service then
* broadcasts the event to all subscribers that have subscribed to the service that broadcasted the event. The
* web socket service only has information about who is connected. Each connection to the web socket service
* is called a subscriber. Subscribers can be either a service or a web client. When a token is created and
* given to the subscriber class using the "save_token" method, the subscriber is a web client. When the
* method used is "save_service_token", the subscriber is still a subscriber but now has elevated privileges.
* Each service can still subscribe to other events from other services just like regular subscribers. But,
* services have the added ability to broadcast events to other subscribers.
*
* Line 1 of this file allows the script to be executable
