      Args:
          context: dictionary-like. context is mandatory.
                   context must contain key 'echoMe'
                   context['echoMe'] will echo the value to logger.
                   This logger could well be stdout.
  
      When you execute the pipeline, it should look something like this:
      pypyr [name here] 'echoMe=test', assuming a keyvaluepair context parser.
