trait Logger extends AnyRef
A logger through which to provide feedback to the user about a run.
The difference between the event handler and the logger is that the event handler is for events intended to be consumed by the client software whereas the logger is for messages intended to be consumed by the client *user* (i.e., a human).
Implementations of this interface must be thread-safe.
