Implement "Navigation" pattern

Implement a pattern for site navigation which can be re-used by other webapps being developed by

We are expecting to implement at least the top-bar with the University logo and the webapp / site name, as seen in the Cambridge Web Platform site.

Existing inspiration:

• The salary scales application which is currently being replaced does contain the navigation bar element below the logo, e.g. "People Strategy", "HR Services"
• The Regents House Ballots app currently does not have a "top nav" section
• The Web Platform showcase site does have a top nav: "content types" and "example content"
