Re:Clojure and Deps.edn: A basic guide

I think that while leiningen does a lot of what tools.deps/deps.edn and the CLI tools do, the reverse is not true.
tools.deps/deps.edn is about building a classpath to run a clojure process. The clojure CLI tools has some additional machinery for starting a simple REPL. That's it.
What this allows is a potentially more composable ecosystem, where instead of having every new build tool implement a way of declaring dependencies and building a classpath, they could instead use tools.deps + deps.edn.
It also has a slightly different feature set, allowing local dirs and remote git repos to act as first-class deps.
Lein and boot are incumbent, and have legacy projects to think about, so they can't go about just adopting deps.edn + tools.deps without breaking things. So at the moment, things are a bit fragmented. C'est la vie.
