Well, I required a function to mimick a human shuffle.
Because the online shuffle was to help the user predict what sort/types of
deals he would get with a given deck based upon a normal human shuffle.
Plus, I've heard some bad things about shuffle, and of course, shuffe
doesn't mimick a non-perfect human shuffle.
