This is a great addition. Two points:

• We've been using logback for logging in the main codebase, and we might want to stick to that elsewhere.
• It would be great if "example project" code like this could include integration tests that actually set up an index and put and retrieve stuff from it. I know that that's not always trivial, and I'm not suggesting that we should wait on it, but that could be a ticket for future work.

Re: logback, I'll start using that. Thanks for the tip.

Re: the integration tests, I still need to add a solr integration test for the main fcrepo-camel code. Once that is set up, I can reuse the same setup. I've added a pivotal story for this: https://www.pivotaltracker.com/s/projects/684825/stories/82351422

Great! I think that the "message-consumer" project may have some Solr-setup code that could be useful as an example for that.

Where does this PR stand? Any reason not to merge it?

It can be merged whenever. I have some more examples to add, but that's no reason to hold this up
