CGI Demo 2

Just like CGI Demo 1, except it must be a different program.  You get
points for demonstrating this program in class.  Do not submit it to
GradeBot.

Write a CGI program.  It can be anything.  It must demonstrate that
CGI works on your server.

A working CGI program must produce a form on the target machine (the
client on which you are running the web browser).  The form must
include text blanks or radio buttons or something that provides a
method of input.  After entering this information, the form should
send it back to your server, where your CGI program processes the
input and creates a new, updated image on the browser.
