+ ** Excel export format implementation using POI library, but with modifications
+ ** to actually stream output rather than use any temp files.
+ **
+ ** For a rough outline:
+ ** - create a basically empty Excel workbook using POI - empty meaning, without
+ ** data rows.
+ ** - have POI write that workbook out into a byte[] - which will be a zip full
+ ** of xml (e.g., xlsx).
+ ** - then open a new ZipOutputStream wrapper around the OutputStream we took in
+ ** as the report destination (e.g., streamed into storage or http output)
+ ** - Copy over all entries from the xlsx into our new zip-output-stream, other than
+ ** ones that are the actual sheets that we want to put data into.
+ ** - For the sheet entries, use the StreamedPoiSheetWriter class to write the
+ ** report's data directly out as Excel XML (not using POI).
+ ** - Pivot tables require a bit of an additional hack - to write a "pivot cache
+ ** definition", which, while we won't put all the data in it (because we'll tell
+ ** it refreshOnLoad="true"), we will at least need to know how many cols & rows
+ ** are in the data-sheet (which we wouldn't know until we streamed that sheet!)
