Devices fix
Begun implementing overview functionality for the temperature
Begun implementing functionality to retrieve data from the database and JSON files. I've also removed Servles that are of no use to the project (they were created to help connect to the MySQL database using JDBC).
Made amendments to codebase and file paths, that weren't originally working properly.
Implemented functionality that sorts data by weekday, and averages that data for each individual weekday, regardless what type of context (i.e., temperature) it uses. It currently features functionality to write an overview of temperature data. I've also DELETED a Database class, which was created when I started the project, which is no longer requrired. Whew!
