Handler class

Composes a LogFormatter, a LogSink, and optional filters and decorators.

The Handler is the central orchestration unit in the logging pipeline. It filters incoming LogEntrys, transforms them using a LogFormatter, applies a sequence of LogDecorators, and finally sends the results to a LogSink.
