Document example of passing data from child to parent

[WildOrangutan]

Hey,

would it be possible to add a simple example in documentation, that demonstrates how to pass result from child to parent, when using Appyx navigation?

Or maybe add a sample in demos/ and link it to documentation.

Thank you!

I think you have at least 2 simple variants:

1. Pass state from Parent Node to Child Node in constructor and collect state changes in real time wherever you need
2. Or awaits Node.onChildFinished and get data from finished Child Node

Also there is discussion about same question.
