Support longer Articles

Create a way to split a long article (20, 30 or 40 pages) into a couple of articles. in this case it should generate a outline, then we should set up - or let it do automatically - how long every outline-point should be and then it genereates the whole thing. (in the back it would just generate 5 pages, then the next 5 and so on, but in a way, that the qualitiy is fine:)
