finished the crawler. LVBPoliceTickerCrawler will crawl over the mainpage and store all links ot the article into a csv file (important change path to the file in FileUtil). LVBPoliceTickerDetailViewCrawler will go over the pages stored int the file and extract the url, title, article, snippet (20words + ...), copyright and time published the article. Todo - put the detailview crawler into a thread that runs every x seconds to avoid crashing lvb-onlie.
