Summarize by country, year, and topic

In previous exercises, you summarized the votes dataset by country, by year, and by country-year combination.

Now that you have topic as an additional variable, you can summarize the votes for each combination of country, year, and topic (e.g. for the United States in 2013 on the topic of nuclear weapons.)
