Implemented ResultNodeFacade as a DOM node construction helper

* wraps result node construction and appends it to root node on destruction
* offers a simpler interface for common node construction patterns
* simplifies result node construction in all external function implementations
** most noticeable in FunctionReadDirectory
* expanded FunctionReadDirectory result nodes by name, extension, and full-path nodes
