Per request [#228](https://github.com/react-community/react-navigation/issues/228), I've updated the the Hello Mobile Navigation guide to try and make it more approachable to newcomers like myself. I changed the order of some of the explanations and broke out passing params into its own section. This should make the guide easier to follow as only one new concept is introduced per section; a common principle in teaching methodology.
I'm open to suggestions as I am also a newcomer to both React Native and React Navigation. So it's very possible that there are concepts that I've misunderstood or am not explaining well.
