#Coding Assignment - Scott Dubinsky
category_counter.rb
This is a class that takes a filename, and counts the number of categories that occur in that class. There is also a print method that prints the number of occurrences of each category and what the order was, with duplicates stripped out.
set_counts parses the array of lines to count them by category. It uses a hash with a default of 0 to sum them up.
get_lines takes a string and parses it into an array. It also removes duplicates, missing values, and illegal categories.
print_categories prints the categories.
print prints the output formatted as required.
###runner.rb
This is a small runner file that creates a CategoryCounter object and calls its print method.
##Testing
This project uses minitest for its testing. To run the tests, call $ ruby tests.rb. The test data is in the test_data directory.
