Create an example of a more complex MST Setup

[cdanwards]

From a slack discussion in e-mobx-state-tree:

I need some help on a MST issue I'm running into. I've been discussing with Yulian & Frank about this and haven't been able to find a solution.
Has anyone run into the issue where when you do extend(withRootStore) you start getting a recursion error and all your stores types are any? This seems to happen when you incorporate both actions and views, but not when its one or the other.
Tried to fix using: types.late(...), getParent(self, 1), getRoot(self)...
Here is a link to the issue that Frank put together: [https://snack.expo.dev/@frankcalise/recursive-mst —see comment in character-store.ts](https://snack.expo.dev/@frankcalise/recursive-mst —see comment in character-store.ts)
