Title: Improvements for #5 & #6

Hi,

When I revisit this excellent series of tutorial and code, I found two possible improvements:

1. It's suitable to introduce CountBy to user in #5, as they are ready for optimizations.
2. Use the helper functions in cascading-test to demonstrate Cascading unit tests better.

Please take a review, and merge the pull request if you like it:)

Thanks,
Branky
