Support for heterogeneous graphs

[Mrugankakarte]

Thanks for this wonderful library. In writer.add_graph(), I saw that it only accepts homogeneous graphs, do you have any plans to support heterogeneous graphs?

@Mrugankakarte Thank you for the suggestion. We are aware that supporting heterogeneous graphs can be a promising direction. However, at this point I cannot guarantee if this will be realized and if so when. For the time being, you can encode node types with node classes (colors).

Thanks. Closing this for now.
