 //This function will try to identify the browser. The best way to use this script is to check for IE vs other browsers
 //Text function exists if this is required to return something like a message for the user. This doesnt yet test of
 //other browsers such as Google Chrome, however chrome or other browsers tend to use the rendering engines from one of
 //the tested for browsers so UK (u)n(k)nown should never really arise.
