new module:FeatureOverlayMgr()
Provides a service that wraps an "unmanaged" vector layer, used as a shared vector layer across the application.
Example:
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);
