Add commas to whole numbers (using simple class and methods/instances)

				
'**************************************
' Name: Add commas to whole numbers (using simple class and methods/instances)
' Description:I don't know if this already exists here at PSC, but I had some time on my hand and I wanted to submit this for beginners and intermediates who dislike the idea of "OOP" programming in javascript. When you first look at the code, you may get the impression that all I am doing is using functions and ask yourself why I did what I did. My answer is this, I can pull that class and related prototyped functions/methods out and without any changes to the code, use it else- where. (WOW, sounds abit like C++ OOP and JAVA). Anyway, its more of a learning tool and yes, I did not do a complete validation on the input..just basic. Anyway, hope someone has the need for it and uses it.
