Re: Cleanup beam scoring code. (issue4001046)

LGTM.  Reads a lot cleaner and is much more extensible.

This may be for another patch, but I think one problem that remains with
the algorithm is that the "reasonable_score" parameter may inadvertently
exclude certain quants from receiving a demerit they deserve because
they are not part of a for loop.  More qualified quants then get hit
with a demerit and become less reasonable than the previously
"unreasonable" quant.  I know that taking away the "if" statement that
checks for reasonability would increase computation time, but is there a
better way to assure that non-reasonable scores will not rise to the top
of the pile because they have been excluded from stages of the
penalizing process?
