EnsembleModelProvenance
public class ModelProvenance extends Object implements com.oracle.labs.mlrg.olcut.provenance.ObjectProvenance
Contains provenance information for an instance of a Model.

Made up of the class name of the model object, the date and time it was trained, the provenance of the training data, and the provenance of the trainer.

In addition by default it collects the Java version, OS name and system architecture, along with the running Tribuo version.
