What's New in Bill's Experience Calculator

v1.0
This is the initial version that was functional, but had no error correction.

v1.1
I added a chart showing how experience is determined.  I also added in error
correction so that the program won't crash if you put letters instead of numbers
in the boxes.  Also updated the form handling code so that there would not be 
any parts of the program left in memory after it is closed.
