CompositeLogger class Null safety

Aggregates all loggers from component references under a single component.

It allows to log messages and conveniently send them to multiple destinations.

Example

 MyComponent implements IConfigurable, IReferenceable {
     var _logger = new CompositeLogger();

    void configure(ConfigParams config) {
        _logger.configure(config);
        ...
    }

    void setReferences(IReferences references) {
        _logger.setReferences(references);
        ...
    }

    myMethod(String correlationId) {
        _logger.debug(correlationId, 'Called method mycomponent.mymethod');
        ...
    }
}
