updating index to fix the quickstart so that it actually works. #220

| One of the best practises when working with Formula is to first think what the UI needs for rendering and what | ||
| actions the user will be able to take. This concept is called a `RenderModel` and is represented by a Kotlin data class. | ||

| To get started create a new Android application called `Counter Application` with a blank activity. Next, rename (via refactor) |

Maybe instead of this, I would recommend cloning the repository and going into samples/counter

I wonder if we really need to be so explicit with Create a file called CounterRenderModel in the same package as your activity and add the following content.

I would probably avoid introducing such details as most Android devs should know how to register Application.

I could change this to just mention to remember to update your application to use the new MyApp class.

I wonder if we should include this whole XML, makes the example pretty dense. Maybe it would be enough to include a screenshot of the UI and provide a link to XML layout.

If we want to have an example that a user can follow along with, unless we have a starter project, this is the only other way to do that given that these are referenced in our examples.
I found a bunch of broken stuff in the index documents for Formula. If you try following the example listed in the quick start it also
does not work and is different from the sample project it references. This PR updates that. I also created a separate project here https://github.com/lgleasain/counterexample that reflects what index guides you through creating. We will want to bring that into Formula or as a separate Instacart Public repo. Please let me know if I missed anything or if you have any ideas etc..
