Very basic intro into using ArrayLists to read and load data from .csv files.
No file just simple Array vs. List operations (totaling).
Adding in List of Ints to read in file (no csv just text).
Final version uses a List of Lists (int) which reads and splits data as you would see in a CSV file.
Extra: version uses a List of HashMaps which reads and splits data based on real experiments (sanitized). Then compares this with a List of Classes.
