// This class is a consumer 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.
