Make frbc example take an (optional) url via command line and also make it importable by moving the "action" into an if __name__ == "__main__":

@MauriceHendrix Perhaps a more descriptive approach would be to use argparse https://docs.python.org/3/library/argparse.html
This is a simple CLI utility for Python and will also generate help messages etc.

I know about argparse, was just hoping to avoid brining in another library for the sake of just 1 argument, but perhaps it's better (and you get the --help / -h as well)
