Logger (disco-java-agent-api 0.12.0 API)

```
public interface Logger
```
In a manner similar to Java logging frameworks such as log4j, DiSCo provides a pluggable interface for attaching named loggers e.g. by following the convention of a named logger per named Class, or by electing arbitrary names. Internally DiSCo constructs instances of Loggers named after its Class names, and by default the logging implementation is a Null Logger which has no-op behaviors. Clients may instantiate an instance of the Logger interface, to direct DiSCo's log to a real logging implementation of their choosing - e.g. a simple wrapper around System.out (provided in the disco.agent.reflect package as a courtesy) or by smarter implementations which use the desired logging framework supplied within the service-under-test.
