how to update the layout after adding / removing node and edges ?

[Vincent Berenz <vberenz AT tuebingen.mpg.de>]

Hello,

I am a new happy user of graphstream. It is easy to use and looks great, 
I just have this issue:

- After creating a graph, I call its display function (passing true as 
argument)
- The ui appears and the graph pops out, the layout is applied and looks 
cool
- During later iterations, some node and edges are added or removed. The 
layout is either not applied at all on these new items, or partially 
applied (the graph starts to rearrange, but stops). See attached image.

After the first "display" call, I do not call any method for updating or 
refreshing (should I?).

I run on ubuntu 14.04. The issue is there whether or not I used the 
"ui.quality" attribute.

Anything I may be missing ?

Thanks,

Vincent
