Add argument parsing for usage as a script
Add argument parsing for usage as a script

The script now requires at least one argument, which
must be surrounded by quotation marks.

The script can be executed like so:

  $ ./podcastAnalyzer.py "https://www.google.ca"

(though this example will not work since Google's home page is
not likely to have any podcast data).
