Ajay, thank you very much for picking up that age-old habit of posting summaries.
It existed years ago on s-help and I find it is still a great thing: I would not have bothered to read your original question nor the answers you got, but I did read the summary -- and I learned something quite interesting! Maybe some others who receive multiple non-elementary answers to their questions could sometimes bother to compile a summary so that some of the bystanders be educated at low cost?? Unrealistic? I'd be willing to do it for my own questions if it was at least a little common.
