PR to show how we can use webpack 5

[pmuir]

This is a bit out of date so there are conflicts.

The goal here is to show how to use webpack 5 and then also to expose components over it.

As part of that I had to break up components and make functionality like navigation external to the view.

Raised another Pr with resolved conflicts #209

I will go ahead and close this, since @indraraj has resolved the conflicts in another PR - and has been merged.
