Clear example with top-level Redux `connect`

[adamski]

I'm struggling to work out how to access redux state from a connected component's props, using the top level method connecting it to the Router.
I'd like to avoid using multiple connects, as the Redux docs state:

Try to only do this for a top-level component, or route handlers

I'm refactoring some code using NavigatorIOS and was previously passing the necessary props using passProps. I can't see an equivalent - I guess that happens behind the scenes with connect? Or do I need to connect each Route's component?

Think I found some good advice on #56
Still would be good to have clearer example I think.

Feel free to submit PR for improving documentation. Btw, there is quite large discussion at redux github about having only one connect for top-level component, and i don't agree with this sentence.
