''Description: A simple example of creating a basic calculator.
'
'Updated Copyright: 2007, December 14th
'
''Update v1.1: Made it to where the text would clear before adding a new number after a calculation has taken
'place. Example: If you click 1 + 1 and then the = button, it will display 2. Before this update if you
'pressed another number it would add to the number that was calculated. But now it will clear the previous
'calculation and then add the pressed number.
'
'Other: For some reason I didn't add a 0 button. I guess I didn't do it because the layout of the
'form would need to be redone. Anyways this is only a example, so a newly made calculator can add
'its own 0 button. :)
