Hi Brendan --

This will be a "constant gardening" operation.  Every day, we'll be  
looking for ISBN-10 and automatically converting them to ISBN-13.  So  
as a user, you won't really have to worry about it: just add either  
one, and we'll fix it if it's the "wrong" format.

Adding the docstring to the property is a good idea, nonetheless.   
We'll add it.
