* Change Request #7
Requestor:  Ninfa Pendleton - Rapid City, SD
Write the program in Java (with a graphical user interface)
and have it calculate and display 
the mortgage payment amount from user input of the 
amount of the mortgage and the user's selection from 
a menu of available mortgage loans: 

- 7 years at 5.35%
- 15 years at 5.5%
- 30 years at 5.75%

Use an array for the mortgage data for the different loans. 
Read the interest rates to fill the array from a sequential file. 
Display the mortgage payment amount followed by the loan balance and 
interest paid for each payment over the term of the loan. Add graphics 
in the form of a chart. Allow the user to loop back and enter a new amount 
and make a new selection or quit. Please insert comments in the program to
document the program.
