org.locationtech.udig.catalog.IGeoResource.canResolve()
Harded coded to capture the IGeoResource contract.
That is we *must* resolve the following:
Required adaptions:
- GeoResource.class - this
- IGeoResourceInfo.class - getInfo (ie about this handles contents)
- IService.class - service (ie that is responsible for this GeoResource)
Recommendated adaptions:
- ImageDescriptor.class (for icon provided by external service)
- List.class - members (ie children of this georesource as in the wms layer case)
Here is an implementation example (for something that can adapt to ImageDescriptor and FeatureSource):
```
  public <T> boolean canResolve( Class<T> adaptee ) { return adaptee != null && (adaptee.isAssignableFrom(ImageDescriptor.class) || adaptee.isAssignableFrom(FeatureSource.class) || super.canResolve(adaptee)); }  
```

                    // dumpMap(coverage2D, fileCrs, newCrs, mapPath, isAscii, isTiff);
                    // }
                    // }
                    //
                    // } else
                    if (geoResource.canResolve(GridCoverage.class)) {
                        GridCoverage2D coverage2D = (GridCoverage2D) geoResource.resolve(GridCoverage.class, pm);
                        dumpMap(coverage2D, fileCrs, newCrs, newPath, isAscii, isTiff);
                    } else {
                        throw new IOException("The selected resource doesn't seem to be a coverage layer: " + geoResource.getTitle());
                    }
