    public class WekaEvaluationValuePicker
extends adams.flow.transformer.AbstractTransformer
    Picks a specific value from an evaluation object.

    Input/output:
    - accepts:
       weka.classifiers.Evaluation
    - generates:
       java.lang.Double


    Valid options are: 

    -D (property: debug)
    If set to true, scheme may output additional info to the console.
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: EvaluationValuePicker
 
    -annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
