Assignment 7

1. GUI for currency exchange rates. Implement a GUI to allow users to change the currency exchange rates used in assignment 6. The user should be able to enter new a new currency. The GUI is being developed for users that are authorized to modify the exchange rates, so there is no need to provide a level of authentication or security.

2. Saving the currency exchange rates. When the exchange rates are changed save the new rates in a file separate from the image. Of course saving the rates in a file is not useful if the contents of the file are never used. When money is changed from one currency to another the file or a cached version of the file is to be used to compute the exchange in currency.
