public class ShapefileWriter
Writes out a treemap as a collection of ESRI shapefiles. A shapefile consists of 3 separate
files - name.shp containing the geometry; name.shx
containing the file offsets for the components that make up the geometry; and
name.dbf containing the attributes.
There should be no need to call the constructor explicitly since
all methods are static.
public static boolean writeNodes(TreeMapNode node,
Writes a shapefile based on the supplied treemap node (and all of its decendents).
The given fileName can be supplied with or without an extension, but this method will
write three files with the same base and extensions .shp, .shx
node - Treemap node to write.
fileName - Name of core of the three files to create.
