/**
 * Write a guessing game which prompts a user to guess a mystery number within some range.
After every guess the program should display some variation of "too large", "too small", "correct guess", respectively.
Upon termination, the program should display the number of guesses before successfully guessing correctly.
A number that is input consecutively, should register as a single guess.
