"""
This is the screenscraper for planning apps for 
Barnsley Metropolitan Borough Council.

The apps for Barnsley are displayed in html pages one per week, starting on
monday. There is no date_received, so we'll have to use the date of the 
start of this week.

There is no comment url, so we'll use the email address.
