Dont print info by default

It would be nice if there was a verbose option to turn on the info-printing but have it be quiet by default.

What about if we change those to debug? In a bigger picture, we should have some kind of logging system so that we can write messages to log files. Also, it would be nice to control the number of logging messages based on that is user executing functions interactively in REPL or running them from the script file.

Debug probably also works, but I am not very familiar with the Base Logging system.

I agree that changing these messages to debug is a good idea. Maybe leave the warnings as they are though (or change those to info if they are not very important).

If a user wants to write messages to log files they can easily substitute the base logging with e.g. Memento. This means we can continue to use base logging and let users decide what they want to do with their logs.
