Feature request: Per node/edge attributes

[josqu4red]

Great library!

It would be awesome to support per-resource attributes, to highlight relations between different sub-systems, for instance.

It would be good to support them. But I have no idea how to support per edge attributes. Per node attribute is very easy, EC2('name', attr=...) for instance. But the edge only can be made by shift operator now, so there is no place to inject the attribute.

Any idea?

Could you do something where if the shifted target is a string treat it as a edge label?

EC2("MyNode") >> "EdgeNote" >> EC2("OtherNode")

For more advanced attributes, a formal object could be used?

attr = Attribute(dashed=True, color="pantone-448-c", label="Goes here")
node >> attr >> other_node
