To be frank I don't know what this page should contain. But since you are here let me say some thing to you. We make no claim that whatever is written here on this website is our work. Most of the things have been inspired [or copied would be a better word] from different sources. But still there are several ideas which we have incorporated from our sides. We have tried to give as many references as possible, but may be some people are left. So we hereby apologize to all of them.
