Suggestion: use log

[jamestwebber]

Hey, thanks for creating this port, this is super useful for me!

Once thing that I would appreciate is an ability to silence the output. I'd like to use this tool in another library but I will be calling it many, many times. Getting all of these progress messages for every query would be a big pain.

If you used the log crate instead of eprintln it would be easy to silence those messages (if you want to keep them at all).

What is the status of this project? Are you interested in PRs?
