    Rewrite GeneratorSource as a trivial class.
    
    Since I originally wrote it, I've introduced BracketingGenerator and
    BinaryIntervalSource, which are more or less designed to be connected
    back to back with maximum convenience - a pattern that already appears
    in GammaWrapper and MonotoneHelper.
    
    Replacing the special-purpose implementation of GeneratorSource with
    the completely trivial class that just links those two together not
    only simplifies the code, but also makes it faster - computing
    W(1000000) to 70 decimal places is now more than twice as fast.
