/**
 * Dashboard class is the GWT Entry point classes that define
 * <code>onModuleLoad()</code>. <br>
 * The class uses the {@link DashboardService#getCurrentViewSettings()} to load
 * the user preferences on load time and once the settings is loaded, it begins
 * to draw the {@link ODBChart} for each graph
 * <p>
 * The class registers a {@link PushEventListener} listener to listen to the
 * events fired by the
 * {@link ActionProcessor#firePushEventAction(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)}
 * . <br>
 * Once the event is fired, the
 * {@link DashboardService#getDataUpdate(String, String)} get called. and the
 * chart the updated with the {@link ODBChart#updateChartData(DataVO, Label)}
 * <p>
 * Note that this class is a part of the client package. And hence, it will be
 * converted to Javascript code in the "GWT compilation" process
 * <p>
