//                                     SEMESTER 2 2001

// This program is an advanced version of the payroll application in the semester 1
// assignment.  It uses Object Oriented Programming (OOP) to enhance the funtionality
// and expand on the usefullness of the previous attempt.

// FEARURES

// You can create new payrolls, view them or edit them if you made a mistake.  The payroll
// can then be saved to be accessed or modified later at your leisure.  The easy to use 
// graphical interface and simple yet elegant design make this program the perfect solution
// to your small buisiness payroll problems.  Super Payroll Advanced will make your nasty
// yet essential book-keeping hours be done in just minuites!
