Craigswatch (a craigslist watcher)

Craigswatch is a module that allows a user to watch for selected items to appear on craigslist. He selects a location (perhaps "US nevada las vegas") and a category (perhaps "for sale cars+trucks") and enters from one to three search terms (perhaps 'honda', 'accord'). If the cron is set up to run every hour, the craigswatch module will scan the first 100 postings (the first page) of the craigslist page for "US nevada las vegas for sale cars+trucks" listings. It will then filter out any listings that contain the words "honda" and "accord" and create a listing record for the user. Also, an email will be sent (assuming he checked the "send email" box) alerting him that the item has just been posted. He can then go to the site to "view/edit/delete" his watches, and to "view/delete" his listings.
