Sample Class (to see what's possible)

As noted in the comments, but it's worth highlighting:

FOR THIS WHOLE PROGRAM REMEMBER THIS IS JUST TO SHOW YOU THE KINDS OF THINGS PROGRAMS CAN DO

YOU ARE NOT EXPECTED TO UNDERSTAND OR BE ABLE TO REMEMBER MUCH OF THIS AT ALL (At this point.)

Never-the-less, I will comment briefly on the various parts which I mentioned in class.
