 Contract: guess :  void -> int
 Purpose: expects nothing, flakily-randomly
    chooses a number between 1 and 100, and asks the
    user to guess what it is, until he/she does;
    then it returns the number of guesses it took

 Examples: 
    for  guess()
    ...if it takes me 3 guesses to guess the number,
    then  guess() == 3
