Basically added StackMapTable attribute. The class is huge in terms of
the amount of codes, and it is not structured well. There may be errors
exist in the codes since too much added codes have not been properly
tested. It would be a great idea to work on testing with binary data in
the future. But for now i hope to get it done asap without experiencing
too much trouble. Although it is rare that the codes run without
crashing, i hope it does.
