Program description: How this program works is by using multithreading to my advantage! I use 4 for loops that goes
                     through the ascii characters determined by the built in string functions by Python. This is more
                     efficient than my bikelock program because it is doing multiple different attempts AT THE SAME TIME.
                     It goes through lowercase and uppercase letters first and then checks for cases with special
                     characters.
