    public class WekaDatasetsMerge
    extends AbstractTransformer
    implements WekaMergeInstancesActor
    Merges 2 or more datasets into a single dataset, under a selectable merge method.

    - accepts:
    - generates:

    -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: WekaDatasetsMerge
    -annotation <adams.core.base.BaseAnnotation> (property: annotations)
        The annotations to attach to this actor.
    -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
        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
    -method <adams.flow.transformer.wekadatasetsmerge.AbstractMerge> (property: mergeMethod)
        The method that should be used to perform the merge.
        default: adams.flow.transformer.wekadatasetsmerge.Simple

    Merges two or more datasets into a single dataset using the specified merge method.
