How do you debug in Python? Coming from a Matlab and R user. I'm already aware of pdb.

Here's you're setting attributes (which is a very normal thing to do).

I think this "employee" is called "person" in the code the traceback 
came from. It is better when these two things match.

Here's you're trying to index another object using a string, which seems 
to resemble the .created_at attribute in your PERSONDatabase object.

I would presume from this that the "person" object at the bottom of the 
traceback is the "raw_person" called above it. But I do not see 
raw_person defined anywhere. Are you sure you didn't mean to pass 
"raw_neo" instead of "raw_person"? That would be more normal, since 
you're iterating over "raw_objects".
