/*
** The Visualizer class is used to create files that may be used as input for
** gnuplot so that the nodes locations and packet routes may be visualized.
**
** The class must be instantiated with either the base name of the files to
** be created or with no arguments, in which case no output is generated.
**
** Files created
** baseName.nodes: location of all nodes
** baseName.paths: all of the routes taken by successful packets
** baseName.drops: all of the routes taken by packet that were eventually
**		   dropped.
