// TO DO: write runPayroll() method which prints a header saying
//"XXX Payroll" where XXX is the month, then reads each record
//in the staff file and for each prints an advice of the form:
//
//Salary advice for Freda Bloggs
//Employee number: 42
//Employee grade: 6
//Monthly salary: ?400

//and finally returns the total cost of the month's payroll
