First draft of object model chapter

Would it be possible to improve the wording of this sentence? I must admit I re-read it and the next bit of code a few times to understand it. Specifically, `TYPE is the class of almost all classes. Thus both TYPE and OBJECT are instances of TYPE.` is not an apparent relationship. I had difficulty intuiting what the relationship is when there is the `almost all classes` bit. Which is this not true for? Why is it thus?
