In Chapter 1, a model directory structure composed of three subdirectories is introduced. In the same vein, although it might seem redundant, it looks to be desirable to introduce a directory hierarchy for the code files introduced in Chapter 2 and to specify which files go where.

Edit: I just noticed that on p24, there is a note explicitly mentioning that there will be no directory structure to be introduced in this chapter. So please disregard this comment.
