Limit a query to a maximum number.
Many web-services have a per-day query limit (e.g. 500 per day for ISBNdb). It is difficult to implement this across multiple invocations of the query objects and Python interpreter, but this can serve as a crude implementation. By default, it raises an exception if the limit is reached.

Have fewer queries been posted than the limit? Note that if multiple queries simulatanoeusly test via this function, exceeding the limit is possible.
