    public class WekaCrossValidationClustererEvaluator
extends AbstractCallableWekaClustererEvaluator
implements Randomizable
    Cross-validates a clusterer on an incoming dataset. The clusterer setup being used in the evaluation is a callable 'Clusterer' actor.

    Input/output:
    - accepts:
       weka.core.Instances
    - generates:
       adams.flow.container.WekaClusterEvaluationContainer

    -clusterer <adams.flow.core.CallableActorReference> (property: clusterer)
    The callable clusterer actor to cross-validate on the input data.
    default: WekaClustererSetup
 
    -seed <long> (property: seed)
    The seed value for the cross-validation (used for randomization).
    default: 1
 
    -folds <int> (property: folds)
