        :type hash_key: int|long|float|str|unicode
        :param hash_key: The HashKey of the requested item.  The
            type of the value must match the type defined in the
            schema for the table.

        :type range_key_condition: dict
        :param range_key_condition: A dict where the key is either
            a scalar value appropriate for the RangeKey in the schema
            of the database or a tuple of such values.  The value 
            associated with this key in the dict will be one of the
            following conditions:

            'EQ'|'LE'|'LT'|'GE'|'GT'|'BEGINS_WITH'|'BETWEEN'

            The only condition which expects or will accept a tuple
            of values is 'BETWEEN', otherwise a scalar value should
            be used as the key in the dict.
        
        :type attributes_to_get: list
        :param attributes_to_get: A list of attribute names.
            If supplied, only the specified attribute names will
            be returned.  Otherwise, all attributes will be returned.

        :type request_limit: int
        :param request_limit: The maximum number of items to retrieve
            from Amazon DynamoDB on each request.  You may want to set
            a specific request_limit based on the provisioned throughput
            of your table.  The default behavior is to retrieve as many
            results as possible per request.

        :type max_results: int
        :param max_results: The maximum number of results that will
            be retrieved from Amazon DynamoDB in total.  For example,
            if you only wanted to see the first 100 results from the
            query, regardless of how many were actually available, you
            could set max_results to 100 and the generator returned
            from the query method will only yeild 100 results max.

        :type consistent_read: bool
        :param consistent_read: If True, a consistent read
            request is issued.  Otherwise, an eventually consistent
            request is issued.

        :type scan_index_forward: bool
        :param scan_index_forward: Specified forward or backward
            traversal of the index.  Default is forward (True).

        :param exclusive_start_key: Primary key of the item from
            which to continue an earlier query.  This would be
            provided as the LastEvaluatedKey in that query.

        :type item_class: Class
        :param item_class: Allows you to override the class used
            to generate the items. This should be a subclass of
