title: Creating UnfoldingMap instance with java.lang.NoSuchFieldError: quality error
body: <p>I try to create PApplet (Processing) with UnfoldingMap (v0.9.6). Unfortunatelly I get <b>java.lang.NoSuchFieldError: quality</b> error at this line:  map = new UnfoldingMap(this, p1). What may be the reason if it?</p>
  
  <pre><code>import de.fhpotsdam.unfolding.UnfoldingMap;
  import de.fhpotsdam.unfolding.providers.AbstractMapProvider;
  import de.fhpotsdam.unfolding.providers.Google;
  import de.fhpotsdam.unfolding.utils.MapUtils;
  import processing.core.PApplet;
  
  public class MyPApplet2 extends PApplet{
  
      UnfoldingMap map;
  
      public static void main(String[] args) {
          PApplet.main(new String[] {MyPApplet2.class.getName() });
      }
  
      public void settings() {
          size(400, 400, P2D);
      }
  
      public void setup() {
          AbstractMapProvider p1 = new Google.GoogleTerrainProvider();
          map = new UnfoldingMap(this, p1);
          MapUtils.createDefaultEventDispatcher(this, map);       
      }

          map.draw();
