How to determine if your web page is being displayed inside the browser
Note: This is a very specific use case. The problem this script solves is: How do you know if you are within a universal co-browsing session or not?
If you have a page, for example, that should be in any way different when you are using universal co-browsing then you can use this script to find out whether you are in a universal co-browsing session or not. For example, if you wanted an area on a page to contain special links, or additional information, that only display when you have started a universal co-browsing session you would use this script to tell you if you are in a universal co-browsing session inside the browser.
The script checks whether you are inside the browser in order that the code you have written that is intended to be universal co-browse-specific will execute in the right place.
