example code is not map to corresponding lesson

[yihaoye]

I use "git clone https://github.com/reactjs/react-router-tutorial" to download the tutorial, however some example codes seem not map to their lesson. Some example codes are map to last lesson.

For example:
react-router-tutorial/lessons/02-rendering-a-route have the same code with react-router-tutorial/lessons/01-setting-up
code in react-router-tutorial/lessons/03-navigating-with-link is for lesson 2
code in react-router-tutorial/lessons/04-nested-routes is for lesson 3
...

please have a check with all example code and modify them.

lesson 01 is introductory and there are no code changes in the first lesson. code changes start from lesson 02.

03 and 04 -> module/App.js files are not same and according to the flow of tutorial.

I don't see any redundancy.
