Commit: "Aggregation Pull Request #1"

• I didn't realize that I had to create a new branch in order to have a separate pull request, hence the aggregation pull request ended up here with the initial test pull request. I have renamed the test pull request to officially be the first pull request in order to avoid any possible confusion.
• I've split the original COVID19 class into two separate classes, UserRequestSetup and COVID19DataRetrieval
• All methods associated with the setup for the user's data retrieval request (selecting sources, send request, etc.) are under the UserRequestSetup class
• All methods associated with the data retrieval process (retrieving by country name/id/code, updates, get all, etc.) are under the COVID19DataRetrieval class
• Methods in the COVID19DataRetrieval class have been reorganized by level of specificity (less specific to more specific) in terms of the details given by the user and the details returned by the SUD as it pertains to the COVID19 case data
• Added additional comments that specify some of the changes made to the code vs the original
• Added additional comments further detailing the functions of each of the methods
• Changed the accessibility settings on various variables and methods for functional and precautionary reasons
• Reorganized and used comments to divide up sections of code and grouping up for possible further aggregation

Further details regarding this pull request will be stated in the report.
