Script to scrape and save NITT student information

The previous commit was the file when I used javascript to emulate
the user, now I am sticking with selenium, which does it job very well!
I used javascript when I worked with the face of the results page,
now that I found the actual url, I have direct access to the
elements in the page.
I have written extensive comments for the main statements.
