[plt-scheme] HTDP Exercise 6.6.2

Looks perfect. This exercise is about learning to package and re- 
package data. Nothing deep.

Let me recommend, however, that you skip exercises that involve draw.ss.
If you can, make up alternatives using image.ss or universe.ss (see  
teachpack
docs). Post them here. Someone will confirm or suggest changes. Then  
solve.
