[GSoC15] Chained Text Boxes - A plan of next milestones

Hi there,
I was thinking of the next important goals for something that can be
(hopefully) merged in master at the end of the Summer and I thought of
sharing publicly my plan.
The estimated times are kinda pessimistic since it is likely I missed some
important.

- Get Underflow working as well as overflow (1-2 weeks)
- Have cursor motion work automatically among chained boxes (1 week)
- Have undo working (1 week)
- Have style sheets preserved and allow # of boxes > 2. (2 weeks)

In the worst case this should keep me busy until around 19th of July.

Cheers,
Matteo
