Graph Operations: Edge contraction and Vertex splitting

Hi!

I am wondering if the graph operations: edge contraction and Vertex splitting https://en.wikipedia.org/wiki/Edge_contraction implemented as procedures? It think it will be handy to have these commonly used operations. Let me know.

Best,

And copyNode with filter perhaps?

Or create a GitHub issue for node splitting with details
