idea: since there will undoubtedly be graphviz properties that aren't first-class properties in Kite, we could hold these extraneous properties in a Dict String String. that way, we should be able to import a .dot file and then export an equivalent .dot, without losing those properties.

i haven't looked at how feasible this is at an implementation level. maybe it complicates things more than it's worth.
