Feature Request - Labels on Connecting Lines

[Michael Rustell]

Thanks Adeel,
This is a really useful package - one of my current favorites. I am wondering whether its possible to add a feature that would allow labels between nodes on the connecting lines. This would be particularly useful if the output could use latex math symbols. In the case of collapseTreeNetwork, perhaps this is just another column for the raw label data, though not sure what is required for latex conversion, if that is possible.
Best regards,
Mike
