Neil,
If you have ideas about how this should be accomplished then outlining them may
provide a reasonable starting point for those new to the code; especially  if
there are any steps that you may clearly see that would help others to make a start.

I've posted this request a few times but the md code is sufficiently
overwhelming that I haven't attempted a solution.

David
