Add Navbar - Githubissues

We need a navbar to accommodate new pages. Considerations include:

Moving the "This site is under construction" notice at the top of the page
Deciding on a color for the navbar that matches the current color scheme, or changing the color scheme entirely. Maybe to something red, for UW?
Considering moving existing functionality to a new page, IE putting different graphs on a new page
