Barabási-Albert model doesn't appear to work

I have tried it for small graphs but it never seems to finish.

```
#r "nuget: Graphoscope, 0.2.0"
open Graphoscope.RandomModels
open Graphoscope
open FGraph

let N = 10
let edgesPerIteration = 2
let myBarabasiAlbert = BarabasiAlbert.initFGraph N edgesPerIteration id id (fun x -> 1.0) FGraph.empty
```
Do you have sample which works?

thanks
