Updated the section on the .vsext export output to include an example of the latest data format from PR #54.
Added figure captions.
Added screencap of Google Chrome directed to the URL in the moreInfoUrl field of the .vsext file.
Added explanation of how to use the new moreInfoUrl and downloadUrl fields.
Clarified the text of the document overall to conform to style conventions of Microsoft Docs which I consider to be very readable by users of all levels.
