Probably not a priority but could we improve the printing of some "basics" like graphs, edges, using cli?

I could not find an open issue about this.

@schochastics beat me by seconds 😆 Thanks for bringing this up @maelle, I think this could make igraph so much friendlier!

I am working on it "offline" since a while but will bump it up on the TODO list a bit
