Examples of IAOIService

org.locationtech.udig.aoi.IAOIService
Service for the AOI (Area of Interest) extent with events to indicate when this value is updated by the user.
To determien the current AOI:
```
 IAOIService service = PlatformGIS.getAOIService(); ReferencedEnvelope extent = service.getExtent();
```
Example of changing the strategy uesd for determining the AOI extent:
```
 AOIProxy proxy = service.findProxy("org.locationtech.udig.ui.aoiAll"); service.setProxy( proxy );
```
