Implementation
We will finally implement persistence. Your application should now be able to load and save the data so that you don't have to re-enter it each run. You may choose whatever method of persistence you wish to use.
We will also display the water quality history graph. The system will prompt a manager for the setup information (like year and location) and then will display the graph results.
Requirements
Provide a way to select saving and loading of system data
Persist (save) the data (serialization, custom text, etc.)
Restore (load) previously saved data
Manager can see option for showing the historical purity report
System prompts the manager for setup information for the report
