Create top navigation bar component

[Schraut]

Directions:

• Navigation bar will go on the top.
• It will include clickable links: RobinHood logo, Products, Learn, Support, Who we are, Log In, and Sign Up

For now, just build the top navigation bar and we'll add links to their pages later as the app grows.

This looks good, I think I can get to it. I'll reply later with a timeframe (story points).

Also open to any other contributors that want to break this apart into smaller story points.
