Thank you Terry,

I went for this solution as it was the easiest for me to understand
and comment myself keeping in mind what level I am at right now.
Thanks a ton to everyone for sharing so much information and making it
easy to read and understand your thoughts. This was surely very very
educating read the replies from so many talented people.

Thanks and looking forward to hanging around here more :)
