[Navigation] Router

[Nefariusek]

As a developer, I want to have a generic router, so I can control which view is rendered.

Acceptance criteria

Verify, consult and update before starting.

• Router is invoked on app load.
• Router listens for an event.
• Router invokes respective render functions based on the location.

Additional notes

• This functionality should be stored in a separate Router.js file.
• Tips: dispatchEvent, location.
