Add initial design along with header/footer

The initial HTML and CSS is introduced with this commit. Header and
footer sections were added to the landing page, with accompanying
styling for the initial design of the site. The idea is to have the
landing page look something like this:

    +---------------------------------+
    | Name           Home Contact Etc |
    |---------------------------------|
    |                                 |
    | Miscellaneous content:          |
    | * github.com                    |
    | * review.whamcloud.com          |
    | * Links to past projects        |
    |   * LLNL ERD Work               |
    |   * Animal Puzzle Adventure     |
    | * Etc.                          |
    |                                 |
    |---------------------------------|
    |         Mail Phone City         |
