 #open(url) - opens and returns an html document
 #css('selector') is just like jquery except server side. It returns a (ruby equivalent of a) linq-like enumerable
 #collect is the same as .NET's select function

 #So this one line when I set url to a Craigslist listing detail page will open that page and return an array of images for that listing.
