Your program will pick a random number between 1 and 100.  Your
program will remember this number but keep it secret.  Your program
will prompt the user to guess a number between 1 and 100 until the
user guesses your program's secret number.  

When the user guesses your program's secret number, the game is over
and your program will print an appropriate message which includes the
number of guesses taken by the user.  When the user enters an
incorrect guess, your program will print an appropriate message and
will say whether the guess was too high or too low.  You will provide
a method by which the user can quit in the middle of a game if he or
she desires.  You will inform the user of how this may be
accomplished.
									    
After each game, your program will prompt the user to input whether he
or she desires another game.  If not, your program will finish.
Otherwise, it will play again.
									    
The computer will choose a new random secret number for each game.
									    
Your program should not assume that the user will always type what you
expect; it must handle bogus inputs gracefully and discard garbage
input.
