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 mentioned above, for the 4 types of patents, for each version, for both granted and applications. Still have to do xpaths for granted version 2.5 for all types, and all applications. Waiting on Oliver about whether we need xpaths for more nodes other than the 6 example nodes.
