        Nice =)

        Cool - well; please construct some larger documents for calc - it'd be
nice if we had some that triggered re-calculation on load too. For
Impress it'd be nice to have some slide-decks with a number of large
images in them etc. Then of course, having the (same?) data in multiple
formats would be a nice comparison point.

        In general it's best to have single files that exercise one feature
each - so we can chart how that feature performs on import over time.

        That looks beautiful =) I assume that between:

        the ~6x slow-down in sample.xlsx is due to the file itself changing ;-)
Oh - also, adding a number format like: #,##0 to each of the callgrind
pseudo-cycle numbers makes it massively more readable =) actually
rounding those numbers to millions of cycles would make them much more
tractable too.

        But hey - this is really awesome progress - really glad to have that
there & generating stats.

        Thanks !

                Michael.
