CompositeFactory class
Aggregates multiple factories into a single factory component. When a new component is requested, it iterates through factories to locate the one able to create the requested component.
This component is used to conveniently keep all supported factories in a single place.
Example
var factory = new CompositeFactory();
factory.add(new DefaultLoggerFactory());
factory.add(new DefaultCountersFactory());
var loggerLocator = new Descriptor('*', 'logger', '*', '*', '1.0');
factory.canCreate(loggerLocator); // Result: Descriptor('pip-service', 'logger', 'null', 'default', '1.0')
factory.create(loggerLocator); // Result: created NullLogger
