Get a successor node from source with a specific label

[kavuri]

I know there is no way to retrieve a node given an edge label, but I am constantly hitting a use case of trying to get a successor node with a given label. Consider a graph representation like:

g.setNode("1", "foo");
g.setNode("2", "bar");
g.setNode("3", "xyz");
g.setNode("4", "pqr");
g.setEdge("1", "2", {label:"time"});
g.setEdge("1", "3", {label: "space"});
g.setEdge("1", "4", {label":"cont"});

I was thinking of something like,
const c = g.getSuccessor("1", {label:"time"}); // returns "2"

The signature would be something like g.getSuccessor(<nodeName>, <edgeLabel>)

I understand that the edges are unique, but maybe leave it to the API user? Is this something that is possible?
