What package is the "groupBy" code in?

I'm not very familiar with the Java codebase. What package / class is
the code for the "groupBy" attribute in?

Thanks,
Ron

Groupby code is found in BasicResultMap. If you pay attention to the 
groupByProps and nestedResultMaps fields, you'll get the hang of what it's 
doing.

The code isn't modularized very well....but it's very fast. it only iterates 
over the result set once (no matter how deep or wide the mappings are), 
which I believe is key to N+1 solution performance.
