/**
 * This class provides a framework for demo application. You should load the
 * true mdb database with predefined "Networkset" dataset. The valence renderer
 * allows the user to display simple junctions based on the number of connected
 * edges. The code also demonstrates how to limit renderers to a specific set of
 * feature classes (in this case, simple junctions). This sample also creates a
 * working entry for the rendered layer that appears in the Table of Contents
 * and will display in a legend.
