Things I've changed

• Removed the calling of menu(); method the second time in the main class constructor 
• Inserted pre and post conditions throughout the program (for documentation purposes - really just for the marks but they do help in programming, especially cause we won't be there to be tech support next year). 
• Inserted a bunch of comments throughout the code telling an EA member what it's doing (and what order it is reading it in as). 
• Added a line of code adding the northIcons to to gridPanelNorth (....that's why it wasn't displaying - because I didn't even bloody add them, sheesh!). 
• Created a JScrollPane in the the displayMethod (in other words, there's no need for any additional clicking, just scrolling)
