This script is used to create an event for DomContentLoaded, which executes PRIOR to the page onLoad event.  It is ideal to run this initialization javascript on the DomContentLoaded (refered to in this script as the Init() function) because it minimizes the possibility of browser flicker.  

There is an issue with IE though, which is why we check the page protocol.  For HTTPS pages, an external script is included to get around the issue that
javascript:void(); executes an HTTP request, giving a "Page contains unsecure items" warning.  By including the external script, we get around this issue.  We only do this when needed though, which is on the HTTPS pages, since this method has the potential to introduce page flicker due to the time needed to load an external script.
