Logging.

In Composer, algorithms and callbacks can make calls to the Logger, which then routes the calls to the appropriate LoggerCallbacks. The LoggerCallback does the actual logging, for example to a file, or Weights and Biases.

See the LoggerCallback documentation for an example of how to define a custom logger and use it when training.
