Here's the patch for this, which contains the newly generated PTypeFamily and Conversions files. I also checked in the scripts I used to generate them, should they prove handy in the future.

> Biting the bullet and generating PType support for all of the Scala Tuple types-- except for Tuple1. I'm going to draw the line there. Along with that, I'm generalizing the ProductAggregator so that aggregations can be performed over Tuples of any arity, and even theoretically case classes.
