/**
* An implementation of GraphGenerator used to generate a graph representing a
* directed line network. Graphs are generated by supplying the generator with
* objects of type LineSegment via the add(Object) method. <BR>
* <BR>
* For each line segment added, an edge in the graph is created. The builder
* records the end coordinates of each line added, and maintains a map of
* coordinates to nodes, creating nodes when neccessary.<BR>
* <BR>
* Edges created by the generator are of type BasicDirectedEdge and contain an
* object of type LineSegment.<BR>
* Nodes created by the generator are of type BasicDirectedXYNode and contain
* an object of type Coordinate.
