Add support for extraction of change tracking info from Excel files

[allanlewis]

Would it be possible to add support for reading change tracking information from Excel files?

What I mean is, if change tracking was turned on in Excel, it should be possible to read the change history of the file, including metadata like which changed have been reviews and which haven't.

I'm using Excel 2010 & 2013, so I'm mostly thinking of XLSX files here. According to the XML schema (available from ECMA), there is an element named revisions of type CT_Revisions that appears to hold the relevant data.

Specifically, it would be great if we could have a revisions method that works in a similar way to the existing comment and comments methods, i.e. s.revisions returns all the revisions, and s.revision(row, col) returns any revisions for the specified cell.

This is an interesting feature request. Anyone interested in implementing it?

Based on the lack of interest,I recommend closing this issue.

I'm currently considering this issue and #185 as part of a future upgrade to Roo.

Closing due to lack of interest.
