> - The `select` method gets called when the user clicks on an edge. `LineWidget` represents a single connection going out of a node and connecting to one or more nodes (one-to-many). `LineWidget` has a list of `Connection`'s that each represent a single link between two nodes (one-to-one). For each `connection` we collect the from/to `Vertex` (superclass for a node) and put them into a set that we then use to select the nodes that are connected to the user-clicked `LineWidget`.
