This sample is the ASP.NET version of our classic ASP wizard. In the classic
ASP version, the bulk of the script's code dealt with maintaining the form's state
from page to page. Since ASP.NET handles the viewstate for us, we're left to focus
on the display of the different pages and handling the button click events.
In the real world you'd want to add some validation, but aside from that and
having it actually do something with the data, the script is pretty much ready to use.
