Flag for page-per-week?
Stats per-week? Maybe tricky, have to copy the aray.
Stats to-this-week - just have to work out in show_results (where we have thisweek defined) what final_idx(thisweek) is, because
  the sort_stats() routine can take a final array element to sort. 

New strategy proposal:
actual.work 1 25 Jul 09 00 25 Jul 14 00 # In the office (1)
actual.work 3 25 Jul 14 00 25 Jul 16 00 # Travelling (2)
actual.work 2 25 Jul 16 00 25 Jul 19 00 # Onsite (3)
These all go on the same line...

I guess this'd mean that:
drink 25 Jul 19 00 25 Jul 23 00
would become
drink 1 25 Jul 19 00 25 Jul 23 00
and so on, for single-state items.







Done:
Statistics - all that's done by the current program. Done.
Tot-up actual.work per week.
