    public class WekaStreamEvaluator
extends AbstractCallableWekaClassifierEvaluator
    Evaluates an incremental classifier on a data stream using prequential evaluation (first evaluate, then train).

    Input/output:
    - accepts:
       weka.core.Instance
    - generates:
       adams.flow.container.WekaEvaluationContainer


    Container information:
    - adams.flow.container.WekaEvaluationContainer: Evaluation, Model, Prediction output 

    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: WekaStreamEvaluator
 
    -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 gets stopped in case this actor encounters an error;
     useful for critical actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console.
    default: false
 
    -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 source with the incremental classifier to evaluate.
    default: WekaClassifierSetup
 
    -no-predictions <boolean> (property: discardPredictions)
    If enabled, the collection of predictions during evaluation is suppressed,
     wich will conserve memory.
    default: false
 
    -interval <int> (property: interval)
    The interval (number of instance objects processed) after which to output 
    evaluation or buffer.
    default: 100
    minimum: 1
