Implemented function to count people

Browse Source 
Honestly I don't like this lesson on dictionaries! This is a perfect use
case for object-oriented programming; dictionaries are just lookup
tables. I think it makes more sense to teach dicts in the context of
price lookups, or passwords, or something that has more structure
than just a place to put names variables.
