/* 
 The most common way to track users in Google Analytics is by using cookies. But sometimes 
 there are platform and security limitations that will not allow cookies to be set or 
 stored for multiple sessions. The following code uses the localStorage property (available 
 now in most browsers) to provide an alternate way to the cookie-based solution. The code 
 is heavily commented to help even the most casual users understand the overall workings 
 of the code. Feel free to ignore this part if you know what you are doing. 
 
This work is based on a Google example:
