    Well, here is a small modification of fpaq0. I changed the predictor to improve speed. Now, instead of keeping counts for each 1 and 0 and calculating a probability of a next bit, new predictor directly operates with a probability of 1.

    Enjoy!

    This program is intended to show a nice approach for modelling - no more no less. I hope Matt will test and add it to his collection!

    I see that Matt has not yet added this to his collection. I assume that its because he's not noticed it yet.
