code: def get_multiple(self, fields=list(), limit=None, order_by=list(), offset=None):

docs: Wrapper method that takes whatever was returned by the _all_inner() generators and chains it in one result
  
          The response can be sorted by passing a list of fields to order_by.
  
          Example:
          get_multiple(order_by=['category', '-created_on']) would sort the category field in ascending order,
          with a secondary sort by created_on in descending order.

          :param limit: Limits the number of records returned
          :param order_by: Sort response based on certain fields
          :param offset: A number of records to skip before returning records (for pagination)
