[Feature Request] Break in arrow for edgelabel.

[cjwyett]

Plots would look a lot neater if the edgelabels were on the line without overlapping.

Image below for context.

P.S. being able to highlight a path would also be nice.

Regarding the "highlighting" feature, I suggest you to possibly change the color of the line rather than highlithting it.
Changing the color of the arrow is already possible by using "edgelabelc".

You could add rectangle object under the edge labels to "break" the edge for the label this would be done in /src/plot.jl.
