Using diff tool

In the code example, I separated each example project into steps. It in encouraged to view the steps with code diff utilities.

For example,

1. Locate the two folders of two steps
2. Select (or drag) the folders to the utility.
3. Compare the code difference between two versions.
4. Repeat step 1 with another two steps.

I believe it is easier to understand how the code is accomplished by gradually understanding each steps. One small chunk of code a time.
