    public class EditDistance
    extends adams.flow.transformer.AbstractTransformer
    Computes the edit distance between the supplied base string and the one passing through, outputting the distance.
    If a string array of length two is passing through, the 1st element is considered the base string instead and the distance computed to the 2nd element.

    Input/output:
    - accepts:
       java.lang.String
       java.lang.String[]
    - generates:
       java.lang.Double


    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
        The logging level for outputting errors and debugging output.
        default: WARNING
        min-user-mode: Expert
     
    -name <java.lang.String> (property: name)
        The name of the actor.
        default: EditDistance
     
    -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
        min-user-mode: Expert
     
    -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
        min-user-mode: Expert
     
    -base <java.lang.String> (property: base)
        The base string to compare against.
        default: 
     
    -allow-transposition <boolean> (property: allowTransposition)
        If enabled, transposition is allowed.
        default: false
