Explain Java terminology before using it

The Deps and CLI Guide and the Using Libs Reference both talk about classpaths without ever introducing what they are or what they mean. In fact, not a lot of the interfacing between Java and Clojure is explained except a little in the Deps and CLI glossary.

@seancorfield pointed to me this really, really excellent guide he made that explains these concepts much more clearly and succinctly than I've seen it explained before. A lot of this has been a complete mystery to me and now I feel like I have somewhat of a grasp on it and I can't tell you how valuable that is.

I've been developing in Clojure professionally for a couple years now and I've never had to know these things (since I have a team with people who generally handle this bit) but having it in such an accessible format would have meant I would have picked it up a lot sooner. 😅

This seems like a classic case of the Curse of Knowledge and a huuuuuuge opportunity to improve the Clojure docs! I'd love to see this integrated into the site somewhere!
