    public class DeleteVariable
extends AbstractTransformer
implements VariableUpdater
    Removes a variable by name or the variables that match the regular expression. Each time a token passes through, the deletion process occurs.
    The transformer just forwards tokens that it receives after the deletion process.

    Input/output:
    - accepts:
       adams.flow.core.Unknown
    - generates:
       adams.flow.core.Unknown


    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING

    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded

    -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
 
    -type <NAME|REGEXP> (property: type)
    How to determine the variable(s) to delete.
    default: NAME
 
    -var-name <adams.core.VariableName> (property: variableName)
