ServiceHost class
Hosts services and provides dependency injection.
There can only be one ServiceHost in an application. Use this code in your main function:
await ServiceHost([() => ServiceA(), () => ServiceB()]).run();
This should not be confused with the IoC container provided
by the client library cl_appbase. While providing a similar
pattern for dependency injection, this class also controls the
execution of the application itself, providing a framework for
services to live in.
