The BBB sample shows error throwing and handling using the System.Exception class.
-Does it handle serializing arbitrary exceptions or should it specifically use System.Exception at the moment?
-What happens when there are network errors? Does the Microservice base class attempt retries, etc?
-If so, is it configurable in any way?
-Can calling code differentiate between exceptions thrown by the ClientCallable annotated methods and exceptions thrown by the surrounding Beamable SDK or network?
