 *
 * The application's main component/controller initializes the feature
 * overlay manager with the map:
 *
 *     ngeoFeatureOverlayMgr.init(map);
 *
 * Once initialized, components of the application can use the manager to
 * create a feature overlay, configuring it with specific styles:
 *
 *     let featureOverlay = ngeoFeatureOverlayMgr.getFeatureOverlay();
 *     featureOverlay.setStyle(myStyle);
 *     featureOverlay.addFeature(myFeature);
