     usage: create a new snippet and name it whatever you want
            call it in a document, ideally the one the user is
            redirected to after registration. This snippet will
            check the users data for a current login_home setting,
            if none is present, it populates the fields according
            to the snippet call. It then outputs a link to the users
            Login Home page.
            
            newLHID --> ID of the document you want to set as home
            
            [!SetLoginHomeID? newLHID=`14`!]
