Hi Antheas,
It seems this series is stalled for 3 days shy of a year now. I have an
interest in getting this across the finish line. Will you be continuing
development? If not, I will take what you've started here and finish out
the remaining nits, keeping your original attribution of course.
Cheers,
Derek
