Integrate new Fenix architecture to Demonstrate How it Works

[colintheshots]

Now that we have a prototype of our new architecture using the Reference Browser, it seems important to integrate this new architecture into Fenix to help others see how to apply it in code. I have already received questions about how it works. Providing code examples in Fenix would provide the quickest answer.

I will work Sessions and Search into our new Component architecture with MVI state management. This will help to prevent the growth of technical debt.
