            try {
                console.log("no GA tracker set");
            }
            catch (e) {}
            finally {
                return;
            }
        }

I was tired of searching for an auto events script for multiple GA trackers so I created my own. Still need to test in multiple Browser but confirmed working in Webkit & Mozilla.
