/*
	1) At line 25, add the code for handling charge and total
	2) Fix the output {presently line 29} so that it's correct if only 1 CD is ordered.
	3) {Very optional}  If your order is more than 20 CD's, the alignment of the output
		will be incorrect. use the "field-width" variable creatively, to change the 
		alignment when orders are $100 or more
