positive.code: 
  It is also possible to return one or many response times directly from the script.
  To add custom response time or overwrite the default one add entries to the _times_ object.
  The entries start with a string that names the datasource and number that represents the response time.
  To overwrite the default response time datasource add an entry into _times_ named _response-time_

negative.code: ==== Requirements for the script (run-types)
  Depending on the _run-type_ the script has to provide its results in different ways.
  For minimal scripts with very simple logic _run-type_ _eval_ is the simple option.
  Scripts runing in _eval_ mode have to return a _String_ matching one of the _Status Codes_.
  
  Every time your script is more than a one-liner _run-type_ _exec_ is required.
  Scripts running in _exec_ mode have not to return anything, but they have to add a "status" entry with a _Status Code_ to the _results_ object.
