    public class WekaChooseAttributes
extends adams.flow.transformer.AbstractInteractiveTransformer
implements adams.flow.core.AutomatableInteractiveActor
    Lets the user select attributes interactively to use down the track.
    Internally, a weka.filters.unsupervised.attribute.Remove WEKA filter is constructed from the selection, to remove the attributes that the user didn't select.

    Input/output:
    - accepts:
       weka.core.Instances
    - generates:
       weka.core.Instances

    The annotations to attach to this actor.
    default:
 
    -skip <boolean> (property: skip)

    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
 
    -stop-if-canceled <boolean> (property: stopFlowIfCanceled)

    default: false
 
    -custom-stop-message <java.lang.String> (property: customStopMessage)
    The custom stop message to use in case a user cancelation stops the flow
    (default is the full name of the actor)
    default:
 
    -message <java.lang.String> (property: message)
    The message to display to the user (variables get expanded).
    default: Choose attributes to use
 
    -pre-selection <adams.core.base.BaseRegExp> (property: preSelection)
    The regular expression to use for pre-selecting attributes.
    default: .*
 
    -non-interactive <boolean> (property: nonInteractive)
    If enabled, attributes that match the 'pre-selection' pattern get selected
