An awesome post, I just given this onto a student who was doing a little research on this. And he in fact purchased me dinner because I found it for him.... :).. So let me reword that: Thnkx for the treat! But yeah Thnkx for taking the time to talk about this, I feel strongly about it and enjoy learning more on this topic. If possible, as you gain expertise, would you mind updating your blog with more details? It is extremely helpful for me. Big thumb up for this blogpost!
