*
* This class is a supplier of events.
* The class is just a helper to simplify common tasks in EC
* tests, such as subscribing for a range of events, disconnecting
* from the EC, informing the driver of shutdown messages, etc.
* There are several ways to connect and disconnect this class,
* and it is up to the driver program to use the right one.
* The driver can request that to this class to send a new event,
* a new shutdown event or to become "active" and send a number of
* events at a certain rate.
