== Notes ==

This program uses two session variables 'answer' and 'guesses':[[BR]]
answer: stores a random number between 1 and 100[[BR]]
guesses: stores the number of times the user has guessed for the answer.

It uses one form variable 'input'.  That is from the textbox on the html form.

Basically the program starts out by generating a random number and asking the user to guess it.
Each time the user submits a guess the program checks if they have guessed correctly in which case
it displays an appropriate message and allows the user to press the button to start a new game.  If
the user guesses incorrectly it displays "too high, or two low", shows the number of guesses so far,
and asks the user to guess again.

In the original if statement it probably doesn't need the "or not form.has_key('input')".  That was included just to show how to check for the existence of a form variable.
