DESCRIPTION
      Extracts the domain name from the given URL.

      It's a tad more complex than that. Since I made this command explicitly as a building block for another command (">") it has some quirks to fit my needs. For instance, I usually wanted the domain address with all subdomains ( e.g. I wanted en.wikipedia.org not just wikipedia.org) unless those subdomains corresponded to a search subsection of a website (e.g. I preferred nytimes.com instead of query.nytimes.com). Details are in the code below.

      Here's the basic regexp behind extractDomainName:
      def extractDomainName(url)
          r = url=~(/^(?:\w+:\/\/)?([^\/?]+)(?:\/|\?|$)/) ? $1 : 'Not a valid URL!' 
          r.gsub!(/((?:www)|(?:seek)|(?:query)|(?:search))\.(([^\.]+)\.([^\.]+)(\.([^\.]+))?)/, '\2')
          r.gsub!(/\:\d+$/, '')
      end
