Added ResultNodeFacade constructor overload for root nodes

* the common use case of ResultNodeFacade inside external function implementations is managing the result root node
** this root node can be fetched through the xercesc::DOMDocument instance
** the new alias overload automatically fetches the root node pointer and as such doesn't require a root node parameter
* changed external function implementations accordingly
