Basic information about an edge used to initially create a Graph. Once a graph is
constructed, all of its methods will return Edges instead, which contain additional useful
information.
An edge is specified by which nodes are its "start" and "end." The direction of an edge is
arbitrary, but once set will be handled consistently by the Graph methods.
The edge may also specify internal locations which it passes through on its way between its
endpoints. That is, an edge may curve and does not necessarily represent a physical straight
line.
