    public class WSTransformer
extends AbstractWSClient
implements adams.flow.core.InputConsumer, adams.flow.core.OutputProducer
    Sends data to a webservice and forwards the response.

    Input/output:
    - accepts:
       java.lang.String
    - generates:
       java.lang.String


    Valid options are: 

    -D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: WSTransformer
 
    -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.
 
    -stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
