Title: Discuss motive behind higher-kinded types example before showing the magic

I had a heck of a time understanding the "higher-kinded types" section.

I'm pretty sure I'd have understood it more easily if it had started w/the motivation behind the example. This change adds a little blurb about that early on.

But I'm still not 100% that I actually understand the motivation behind the example. So... keep your skeptic hat on.
