* Added XML code to parse json + convert formatting before exporting as XML + XML Marshall tests
* Add linting fixes
linting errors still present in xmlMarshaller.test.js but, certain keys starting with digits (for example '800ed0') must be enclosed in quotes , so to maintain consistency within the test file I kept all keys enclosed by single quotes.
* fix(lint): unquote, EOF
