Implement logging

[Michael-E-Rose]

In one way or the other, we need to implement logging.

At the very least, it should log which query is beging performed. Another interesting aspect might be to log timings.

It would look like so:

import logging

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')

if verbose:
    logging.getLogger().setLevel(logging.INFO)
else:
    logging.getLogger().setLevel(logging.WARNING)

and then instead of print(), we would always use logging.info().
