min/ max double periods

[Liviu Lalescu]

If you can allow either of 2+2+2+1+1 or 2+2+2+2, this is more complicated. Add an activity split into 2,2,2,1,1, no min days constraints.

It's easy (to enter the data; but it will be a bit slower to generate then Livius variant) if he has got a 5 days week. Just add a 1+1+1+1+1+1+1+1 with weight 0% and consecutive flag.

Oh yes, I forgot. I think it should have nearly the same speed of generation. The explanation why it works if that FET will not place 3 activities in the same day if consecutive if same day is selected.
