Error while computing eigenvectorCentrality

Hi,
I am trying to use jsnx for a project. I am successfully able to maintain and update the graph data structure and use the ported functions to get the values I need. However, when trying to compute the eigenvectorCentrality, I get the following error:

"Uncaught #" (jsnetworkx.js - Line 2)

I can't figure what the issue is since other functions seem to be working just fine with the same graph. This is the syntax I am using

```
jsnx.eigenvectorCentrality(networkXGraph)
```

where networkXGraph holds the graph I am using.

Any help with this would be greatly appreciated.
