Changed default port from 5000, to 8080
Updated CSS according to homework.

  Following the HW4 I updated the CSS accordingly. Also, added the
section for the navigation. This navigation is special in that it
allows the nav to collapse on screen sizes smaller then 480px wide.
Added the main product sections with placeholders.

Added the main product section. This section will
contain the main product plus a video pitch of
what the product is all about.
Added the Actions sections

Added the Actions, statistics, order and share buttons
to the page. At current the page still does not look like
much, but it is coming along.
Put on the finishing touches for part 1 of HW4

Finished up the css of index.html according to the
pdf.
