    public class Touch
    extends AbstractTransformer
    Like the Unix 'touch' command, updates the 'last modified' timestamp of the file coming through.
    By default, it creates the file if it doesn't exist.

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


    -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: Touch
     
    -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 execution at this level gets stopped in case this
        actor encounters an error; the error gets propagated; useful for critical
        actors.
        default: false
     
    -silent <boolean> (property: silent)
        If enabled, then no errors are output in the console; Note: the enclosing
        actor handler must have this enabled as well.
        default: false
     
    -create-file <boolean> (property: createFile)
        If enabled, the file gets created if it doesn't exist.
