Changes

For the above code, I identified (what I think are accurate) xpaths for the nodes of patent number (//us-bibliographic-data-grant/publication-reference/document-id/doc-number), kind (//us-bibliographic-data-grant/publication-reference/document-id/kind), and grant date (//us-bibliographic-data-grant/publication-reference/document-id/date). I am adding the xpaths for these nodes, as well as the others other types of nodes mentioned above, for the 4 types of patents, for each version, for both granted and applications.
