public interface NCLifecycle
```
NLPCraft lifecycle component.
This interface defines lifecycle hooks for user-defined components that are instantiated by NLPCraft like probe components, custom NER parsers and value loaders. This hooks can be used to integrated with various IoC frameworks, control lifecycle of external libraries and systems, perform initialization and cleanup operations, etc.
Note that probe lifecycle components are configured via nlpcraft.probe.lifecycle probe configuration property that accept list of fully qualified class names where each class should implement this interface. See documentation on how to configure a data probe.
