Interesting; their are a number of generators; some of them you need to
configure so they can tell how to "connect" the graph; however I though
BasicLineGraphGenerator was pretty straight forward (the end points of the line
have to be exactly the same).
Please review the test cases for the plugin in order to see examples.
