* This panel allows the user to input information via as many text fields as you want. You simply specify the number of
* textfields you want and pass the names for each of these JTextFields as a parameter when initialising this class. For
* example, to create a window with 2 text fields and two names you would use the following :-
* <pre>
* <p/>
* JTextFieldPanel panel;
* <p/>
* String[] names = new String[2];
* <p/>
* names[0] = "Enter Your Name";
* names[1] = "Enter Your Address";

* panel.setObject(this, 2, names);
