Return value of ALCourtLoader's .matching_courts_in_county

[plocket]

I found the documented return values for ALCourtLoader's .matching_courts_in_county() confusing.

1. When I called all_courts.matching_courts_in_county(...) today, I got a list of tuples, not a list of dictionaries. Maybe I'm misunderstanding python types, but I suspect others would find it confusing, so it may be worth clarifying.
2. I guessed correctly that int was the index value of the court, but I didn't have time to look into what the str is. It might be useful to specify those too.
