Not allow user to open website in multiple windows

jQuery plugin to check if current window is duplicate window,
I createdd this plugin based on timkellypa's answer on stackoverflow
"Stop people having my website loaded on multiple tabs"
https://stackoverflow.com/a/45717724/223752

This plugin works across all browsers IE, Firefox, Microsoft Edge & Google chrome

It is basically checking GUID of the window against value in cookie

Sample usage:

    <script type="text/javascript">
        $(document).ready(function () {
            if (window.IsDuplicate()) {
                alert("this is duplicate window\n\n closing...");
                window.close();
            }
        });
    </script>
