Instead of the specified word/document.xml, we now look for word/document.xml or word/document(number).xml to support a case where the document xml was stored as document2.xml as Word and LibreOffice support it. Bumped version number.

Created CODE_OF_CONDUCT.md

Fixed a bug where nodes were not being checked for undefined before using its nodeValue.

Ported OfficeParser from js to python
