So I have ParseGraph, which takes a Reader and returns a map from a string, which is the source node, to a slice off all the nodes that can go there, or the destinations. So I'm starting a scanner, creating the line number, and then running over the lines. And I'm trimming the spaces for the string, and if it's an empty string, I just ignore it, otherwise I'm parsing the line.
