[igraph] graph with weighted connections between edges

[Jozef Balaz]

Hi,

I’m looking for a way to define graph with weighted connection between edges 
which will be then used by "Community label propagation” function.

There are 3 use-cases: 
* 2 edges are definitely not connected
* 2 edges are definitely connected
* 2 edges may be connected with certain probability

What is the best way to define this in igraph so that community label 
propagation function will take that in consideration in clustering?
Small example will really help.

Thanks a lot for your support
Jozef
