/*
	based on JSTarget function by Roger Johansson, www.456bereastreet.com

	This script finds all anchor tags and checks to see if they link to a file of type val. (where val may = pdf or doc etc)
	if there is an anchor that matches, then the google pagetracker script is attached to the onclick event, so that we can see
	how many documents are downloaded, and which ones are used.
