Adding a Derive API repl example?

[eddique]

More of a documentation discussion, I recently was playing around with making a repl with clap, but had a hard time finding examples of this being done with the derive API. I would like to suggest adding an example of a repl that utilizes derive vs the builder API. I've created a repo here for the discussion, open to any changes or feedback.

Our ideal state is that all of our examples should be available in both builder and derive. If we only have one, we err on the side of builder as its more universally applicable. We are fully open for people to port our builder-only examples to have a derive variant using our existing patterns for this.

Got it, thanks for the reply! I wanted to bring it up here before making a PR, which would just be adding the content of the main.rs in the repo I linked to repl-derive.rs, and adding a repl-derive.md.

From my brief glance, I would recommend also matching code style to existing derive examples.

When linking this in, be sure to remember to link repl-derive.md into the cookbook like the existing repl.md
