    public class WekaTrainTestSetEvaluator
extends AbstractCallableWekaClassifierEvaluator
implements JobRunnerSupporter
    Trains a classifier on an incoming training dataset (from a container) and then evaluates it on the test set (also from a container).
    The classifier setup being used in the evaluation is a callable 'Classifier' actor.

    Input/output:
    - accepts:
       adams.flow.container.WekaTrainTestSetContainer
    - generates:
       adams.flow.container.WekaEvaluationContainer


    Container information:
    - adams.flow.container.WekaTrainTestSetContainer: Train, Test, Seed, FoldNumber, FoldCount, Train original indices, Test original indices
    - adams.flow.container.WekaEvaluationContainer: Evaluation, Model, Prediction output, Original indices, Test data 

    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
    min-user-mode: Expert
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: WekaTrainTestSetEvaluator
 
    -annotation <adams.core.base.BaseAnnotation> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
    default: false
 
    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this
    actor encounters an error; the error gets propagated; useful for critical
    actors.
    default: false
    min-user-mode: Expert
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing
    actor handler must have this enabled as well.
    default: false
    min-user-mode: Expert
 
    -output <weka.classifiers.evaluation.output.prediction.AbstractOutput> (property: output)
    The class for generating prediction output; if 'Null' is used, then an Evaluation
    object is forwarded instead of a String.
    default: weka.classifiers.evaluation.output.prediction.Null
 
    -always-use-container <boolean> (property: alwaysUseContainer)
    If enabled, always outputs an evaluation container.
    default: false
 
    -classifier <adams.flow.core.CallableActorReference> (property: classifier)
    The callable classifier actor to train and evaluate on the test data.
    default: WekaClassifierSetup
 
    -no-predictions <boolean> (property: discardPredictions)
    If enabled, the collection of predictions during evaluation is suppressed,
     wich will conserve memory.
    default: false
 
    -prefer-jobrunner <boolean> (property: preferJobRunner)
    If enabled, tries to offload the processing onto a adams.flow.standalone.JobRunnerInstance.
    default: false
