  This method may be used to retrieve an existing StatsGroup object. The object
  should be specified using a String array specifying the path to use to retrieve the
  object. If a StatsGroup object can not be found using the specified path, a null
  value is returned.
  
  @param path A String array. The string elements in this parameter specify the hierarchy of the stats group being retrieved. If no stats group is found matching the path
  provided, the response object will be null.
