Checks if certain parts of a website have changed in comparison to the last time the script was called. Best to use in cronjobs.
The main function to use is check_site(label, url, selector). selector is the CSS
selector for the website part(s) that you want to monitor. It will then scrape the website at url, extract its textual contents at selector and generate a sha256 hash from these contents. This hash will be compared with a hash that was generated at the previous run and has been loaded from a pickle file prevstates.pickle. If it's not the same hash, a notification email will be sent.
