Title: ISN Data Types

I've been meaning to add AR/Rails support for a subset of PG contrib's [ISN data types](http://www.postgresql.org/docs/9.2/static/isn.html). Specifically, I'd like to add support for the common UPC, ISBN10, and EAN13 types.

Is there any interest? If so, are there any objections to only providing partial compatibility with the module?
