Improved argument resolution and error handling

* execute member method internal argument count checks are not needed when using between one and two arguments
** xalan automatically generates the appropriate message containing the getError message when only offered fixed argument execute member overloads
* improved FunctionReadDirectory attribute element generation
* added additional validations to FunctionReadFile and FunctionReadXMLFile
* I plan to return errors inside a DOM tree alongside the function return values in the future
