raphael Backend operations for email client. This class comprises all methods that manipulate, send or fetch data. The idea is that our focus is on the functionality of the user interface, and not on other functionality. This "other" functionality is collected in this single class "Backend.java". The Backend is used a singleton class. It provides references to the current state of the four main window beans, and wrapper methods for JavaMail functionality, and configuration file load and save.
