code: def get_location(self, location):
          
          return {self.index_name: self._index[location], self.data_name: self._data[location]}
docs: For an index location return a dict of the index and value. This is optimized for speed because
          it does not need to lookup the index location with a search. Also can accept relative indexing from the end of
          the SEries in standard python notation [-3, -2, -1]
  
          :param location: index location in standard python form of positive or negative number
          :return: dictionary
